Other brands of paints! Art Spectrum is the only brand available locally. Winsor Newton I can get from further away, if needed. If your product included these brands, I would gladly pay money for this product.
Apart from that, this is the most amazing thing I have seen to assist painters since standardisation of colours supplied in tubes.

Apart from that, this is the most amazing thing I have seen to assist painters since standardisation of colours supplied in tubes. Maybe I can add a few Winsor & Newton acrylics. Mapping and measuring the colours are very time consuming and therefor it isn't easy to add sets. But I have these is you are interested: Number Name Series Pigments Transparency 019 Azo Yellow Medium 2 Arylamide, PY74 Semi-Transparent 466 Permanent Alizarin Crimson 3 Anthraquinonoid, Dioxazine, PR177, PV23 Transparent 522 Phthalo Green Blue Shade 2 Chlorinated copper phthalocyanine, PG7 Transparent 644 Titanium White 1 Titanium dioxide, PW6 Opaque 664 Ultramarine Blu 1 Complex sodium alumino-silicate containing sulphur, PB29 Transparent 744 Yellow Ochre 1 Natural iron oxide, PY43 Semi-Transparent Cheers Christian

This is great. Is this going to be stand alone program or accessed online only?

Christian,
Paintmaker is great tool.
As a suggestion, Dr. Ph. Martin has a number of aniline dye based watercolors, for example the Radiant Concentrated series (56 colors in 4 sets of 14) that are very popular (commonly used) by airbrush artists. This company also manufactures the Hydrus watercolors, and others.
Unlike acrylics, standard watercolors, and oil paints, the color in the bottle does not match the color on the paper (or illustration board).
It would be a great help with Paintmaker to measure with a spectrophotometer those dyes on the paper after application to the paper and add them to Paintmaker. I suppose a reflectance UV/Vis/NIR spectrophotometer would need to be used in this case. If you can do this, then do a 1/20 dilution at least. 1/50 dilution might be better. 1/10 dilution is still far too concentrated for airbrush. I am currently using a 1/100 dilution (1 part of paint to 99 parts of 70% Isopropyl Alcohol), and when I need to increase color intensity, I simply spray more onto the illustration board.
Perhaps you could add those colors?
In any case, Paintmaker is a great tool and I thank you for developing it.
Best regards, Bob Kerr

Hi Bob I will look into the possibility of adding Dr. Ph. Martin's Radiant Concentrated series. We have been discussing whether we should add airbrush colors so it is very good to hear from you. And thank you for your thorough description of what you use. I will let you know as soon as I know what we do. All the best Christian

Apart from that, this is the most amazing thing I have seen to assist painters since standardisation of colours supplied in tubes. Sorry for answering you question so late. Can I ask what paint from Art Spectrum you are using? Is it oil, acrylic or gouache? Please let know and I will look into preparing them for PaintMaker.

Best regards, Bob Kerr Hi Bob We find it difficult to imagine what good it will do to use PaintMaker with highly transparent paints. Can you tell us how you would use PaintMaker if it could tell you how to mix a color in a 1% dilution on white ground?

Christian, I have increased to 4% dilution. Example: 1ml dye to 25ml diluent. Diluent = 25% Ammonia-free window cleaner + 50% of 70% Isopropyl Alcohol + 25% water. The color of the organic dyes in solution is NOT the color on the board. This is quite different from pigment-based paints. Pigments are ground up rocks composed of the oxides, sulfides, silicates, and so on of metals such as Iron, Zinc, Copper, Chromium, Cadmium, and so on. The source of the color is virtually unaffected by the matrix. The color is virtually completely unaffected by the binders and dispersion agentS such as gum arabic for watercolors , or organic polymer for acrylics [which is Poly(acrylic acid)] or a polymerizing oil such as oil based paints whether or not metallic drying agents are used or not. With these types of paints, you simply mix the colors and what you see on the palette is what will be on the canvas (or paper, or fabric, or board, or whatever).
This is not the case with the aniline based dyes.
It is much more evident when mixtures are being made. For example, flesh-colored tones are quite problematic. Flesh colored tones are basically all mixtures of yellow, red, and blue in different proportion. I can get the flesh colors I need by mixing them up by what I already know to be about the right proportions - but what it looks like in the bottle is NOT what I get on the illustration board.
I will eventually figure out empirically which colors I'm looking for correspond to what specific proportions of individual colors.
I haven't gotten there yet ... but landscape backgrounds - woods, fields, and so on - are probably also going to be somewhat problematic.
I am a beginner in this particular medium - though not overall ...
However, the goal of PaintMaker is to make life easier - especially for beginners at color mixing - and make things go faster - isn't it?
Hence, my suggestion to adapt PaintMaker to this goal.
At least in the USA, Dr. Ph. Martin sells a lot of their dye-based stuff ... so ...
Up to you Christian.
By the way, dye-based colorants have gotten a bad rep for durability and are frequently called "fugitive" colors. This is now a thing of the past. With the development of HALS (Hindered Amine Light Stabilizers) and stable transparent UV absorbers incorporated into a polymeric spray "fixative", fugitive colors are a thing of the past. For example, Lascaux (French) and others have developed fixative sprays that will preserve the colors as long as the paper lasts.
Gotta go.
Bob

Christian,
One last thing, these dyes are not really transparent in the way you're thinking of it.
The dyes are so strong - have such high extinction coefficients, that once laid down, once on the board, they don't 'cover up' very well - or not at all.
Best regards, Bob

Hi Bob We will look into what is possible with the transparent colors. We are all working on PaintMaker for free and out of interest so the development happens in a solid but slow tempo. I hope you have patience. Christian

Online Paintmaker could be very useful. I could use it a lot, every day. But it's gonna be very expensive. $3.49 for 50 credits if extremely high if I want to make maybe 20 or 30 colors for each picture. How about doing this on a monthly subscription? Say $5 per month.

Thanks for making this website, I've enjoyed playing with it so far! I have a question that I emailed you about. I realized it would make more sense to post in the forum in case anyone else has the same question. Which measurement unit is the most accurate: Parts, Percent, or Weight? I noticed they are not consistent with each other. Please see the screenshots attached for a recipe I generated. If you go by Parts, then titanium white is 40%. If you go by Weight, then titanium white is 47.686%. If you go by percent, then titantium white is 43.29%.

We round up the amounts in the part units to avoid silly numbers that is impossible to work with. So part units aren't as precise as weight and percent. Weight and percent are the same and have the highest precision. I don't understand how you can get two different measurements with weight and percent. We use the same data for both. We only change the unit.
Tip: using one of the CAT adjustments will remove the lack of precision using RGB as input. That gives you an even better precision:-)
