Yesterday I made a mistake which is an easy one to make when you’re rushing. I brushed my hand across part of my painting to remove a speck of dust when it wasn’t quite dry. This resulted in rather an annoying pale smudge on an area where I couldn’t possibly add anything in to cover it up!
It could have been pretty fatal had it been darker. I decided to try my Eradicator brush to remove as much as I could before letting it dry thoroughly overnight. The Eradicator brush is a super useful tool, you can buy them from Billy Showell or Jackson’s Art. There is a method to using it which I will explain under the photos below…
If the stain isn’t fully removed (as it wasn’t in my case) leave it to dry overnight before attempting to try again. Don’t panic and keep erasing or you will ruin the paper surface completely.
You can use magic eraser to remove stubborn stains. This is a white foam which I cut into a small wedge shape. This for ease of erasing close to an edge of paint and it is more comfortable to hold whilst working with it.
Once it’s dry you can burnish the area to try and flatten any fibres which are still loose. They may not go away completely but it will feel a little smoother. A second attempt using this method proved successful on my painting, thank goodness! After letting it dry thoroughly I burnished the area again. This is described below.
I used a very fine sanding block to smooth the paper again as the fibres were still obvious. This is only suitable if you don’t want to paint over the area again. If you do, then stick to burnishing and use dry brush method carefully over the area. Washes will lift the fibres again.
If you have any questions please don’t hesitate to contact me with a comment or via my contact details below.
I’m back at last! I have decided to continue on from Blog 25 which discussed Quinacridone Gold across three brands and how very different they all were. It is very easy to make the mistake of thinking different brand pigments will be the same if they have the same name or a very similar name. Some even have the same pigment index number!
In this blog I will be looking at a number of pigment colours across the Daniel Smith and the Winsor & Newton range. All but one have identical names but as you will see many of them are quite different. One colour even shows a difference in temperature, one is warmer and the other cooler. Some are more intense than others, five are completely different!
I am a big fan of W&N as the colour selection, where primaries are concerned, suits me well. Don’t get me wrong I like DS pigments too. DS pigments are beautifully intense and I especially like their iridescent range. These are great for adding shine to butterfly wings. I just feel there is too much choice in the DS range as it is possible to mix every colour you need with 3 blues, 3 reds and 3 yellows. When you mix with primaries, I really don’t think you need 25 reds to choose from, do you? There are also 13 violets in the DS range and I only use 2 from the W&N range, Winsor Violet and Perylene Violet. Some pigment colours across both brands make you think, do you really need them? W&N Ultramarine Violet for instance, why not add a little Winsor Violet to French Ultramarine? Cobalt Violet….a little Quinacridone Magenta mixed with Cobalt Blue will do the trick! Anyway, it’s food for thought.
I have selected 25 W&N pigments for my palette and one DS, Lemon Yellow. The only reason this yellow is there is because it is very like cool Winsor Lemon but DS Lemon Yellow is transparent, not semi-transparent. I generally use 6-9 of my pigments at the most when painting, depending on the subject.
The colours with the same names (except one) that I have selected to compare across these two ranges are listed below:
New Gamboge Indian Yellow Quinacridone Gold Quinacridone Red Permanent Alizarin Crimson Perylene Maroon Burnt Sienna Cobalt Blue French Ultramarine Indanthrene Blue (Indanthrone Blue) Perylene Green Perylene Violet
I have written an outline for each pigment below to show you the differences and qualities. As you will notice below there are four DS pigments which are semi-transparent. I prefer to use transparent or semi-transparent pigments. Some of the differences here are huge but some are actually quite favourable!
(Note: Some photographs are not always a true representation. The DS transparency symbols are different to W&N. Their semi-transparent symbol is a circle which is half black and half white. W&N uses a square which is half white and black but in this brand it means semi-opaque).
New Gamboge DS – Transparent PY97, PY110 W&N – Transparent PR209, PY150 DS – very close to the primary yellow with a slight orange bias. A lovely pure pigment similar to W&N Indian Yellow but nearer to the yellow spectrum. W&N – a muted yellow, similar to Transparent Yellow with a very slight brown bias when at full colour. A little warmer than Transparent Yellow. Makes a beautiful pale cream/yellow when watered down.
Indian Yellow DS – Transparent PY97, PY110 W&N – Transparent PO62, PY139 DS – a cool yellow with translucency. Not what I would consider an Indian Yellow, more like W&N Transparent Yellow or Winsor Yellow Deep. This pigment could be used as a transparent yellow although Nckel Azo is closer. W&N – a rich orange-yellow, flows smoothly and makes beautiful cream/apricot tones when watered down. Great for mixing bright oranges and muting green to an olive/green tone.
Quinacridone Gold DS – Transparent PO48, PY150 W&N – Transparent PR206, PV19, PY150, Be aware W&Nhave run out of index colour PR206 so this will change. It will be replaced with PR179. The name is changing to Transparent Gold Deep. So, if you love Quinacridone Gold buy some now! DS – a warmer, less muted version with a lovely golden glow. It has an orange bias. W&N – a muted, duller QG with a strong warm yellow bias. Rich brown/gold when at full strength.
Quinacridone Red DS – Transparent PV19 W&N – Transparent PR209 DS – a cool magenta/red resembling Permanent Rose (PV19). Quinacridone Red in the DS range is closest to Permanent Rose. W&N – a warm primary red. The match for this red is Quinadridone Coral (PR209) in the DS range. It is quite a weak pigment in both ranges but a beautiful pink/red.
Permanent Alizarin Crimson DS – Transparent PR177, PV19, PR149 W&N – Transparent PR206! Be aware W&N have run out of this index colour so this will change. So if you love Permanent Alizarin Crimson buy some now! DS – a rich intense version of this colour but made with three index colours. It has a slightly warm red bias compared the W&N version which is cooler. W&N – a cool not as intense version which can look a little flat when watered down on some watercolour papers.
Perylene Maroon DS – Semi-Transparent PR179 W&N – Transparent PR179 DS – a rich intense version of this colour. It has a slightly warm red bias compared the W&N version which appears a little cooler. W&N – Nicely intense too. Very slightly cooler than the DS version.
Burnt Sienna DS – Semi-Transparent PBr7 W&N – Transparent PR101 DS – a very different Burnt Sienna to W&N and it appears to granulate. It is also semi-transparent. W&N – one of my favourite reds. A much warmer version than DS. It is more like Pompeii Red (PBr7) in the DS range. I would add a tiny bit of Transparent Yellow (DS Indian Yellow) to Pompeii Red to make it a perfect match!
Cobalt Blue DS – Semi-Transparent PB28 W&N – Semi-transparent PB28 DS – this appears to granulate a little more than the W&N version and is very, very slightly cooler despite having the same index number. W&N – a lovely middle blue, granulating. There seems to be a very slight difference but it is minimal.
French Ultramarine DS – Transparent PB29 W&N – Transparent PB29 DS – a pure primary blue slightly more intense than the W&N version. Granulates. W&N – a vibrant primary blue with no bias. Granulates. The only difference here is the intensity of pigment is greater in DS.
Indanthrene Blue & Indanthrone Blue DS Indanthrone – Transparent PB60 W&N Indanthrene – Semi-transparent PB60 DS – Indanthrone Blue is more like royal blue compared to Indanthrene Blue. It has a very slight red bias. W&N – this version is very different to the DS version. It is a deeper blue with a very slight green bias. They both have the same index number though! These are a nice option for a choice of warm or cool darker blues!
Perylene Green DS – Semi-Transparent PBk31 W&N – Transparent PBk31 DS – very slightly warmer than W&N. It is semi-transparent. Mix it with a rich red like Pyrrol Crimson for a true black. W&N – this version is very similar but it has a very slight blue bias. It is totally transparent. Add a rich red like Permanent Carmine for a true black mix.
Perylene Violet DS – Transparent PV29 W&N – Transparent PB29 DS – a rich pigment but it is more muted than the W&N version, that is, it has duller appearance. W&N – slightly brighter and more intense. It veers more towards the violet spectrum and less towards the brown like DS. A favourite pigment of mine, seen so much in plants! Mix with different yellows for some wonderful muted ochre and brown tones.
As you have seen there are various differences for a number of pigments listed above. There are even slight differences with pigments that have the same index numbers. This variation will most likely be due to different production processes and binders. On one occasion above we saw that a comparison offered up warm and cool versions, W&N Indanthrene Blue and DS Indanthrone Blue. When mixing with these two pigments, the tones would be more muted with Indanthrene Blue and brighter with the DS version. A few DS and W&N pigments have the same name but another colour in the DS range matches more closely.
So, I hope you enjoyed this blog and that it proves useful to you. Thank you for reading and I’ll be back soon with more interesting colour matters.
