If you would like to use my Color Mixing Tools and download the system, please send me an e-mail message, so I can send you the access info. You'll need two files: MCRInstaller.exe and ColorMixingTools.zip. You should download them together, because the version numbers must match. Please note that you are authorized to use the system only according to the Disclaimer below and you are not allowed to put the MATLAB libraries on the internet for any reason. However, please feel free to give the two files to your colleagues or friends, but only for educational purposes.
The current version of the Color Mixing Tools includes more than 25,000 lines of code I've been writing since 2004. It includes 25 paint sets: measured data of 24 paint lines of various brands + 1 ideal set:
Conservation Colors by Gamblin (all colors except “Venetian Red” and “Extender White”: 42 colors): ramps, measurements and parameter extraction were done by Marissa Haddock as part of her Master Thesis at Rochester Institute of Technology in 2011.
Designers Gouache colours by Winsor&Newton (48 bases) (2016, thanks to the ramps and measurements done by Christian Skeel, Copenhagen, Denmark) Some bases have fluorescent behavior, but fluorescence is not computed in CMT: physically mixed paint can be warmer than mathematically computed recipes.
EFX500 by E'TAC (all colors: EFX 501-513 (2007) + 12 colors EFX HS (2009)) Some bases have changed color and formulation over time: these bases can not be mixed correctly anymore.
Ferrario 1919 by Ferrario (30 bases) (2017, thanks to the ramps and measurements done by Angelo Paladini, Tarquinia, Italy)
Heavy Body Artist Colors by Liquitex (22 bases) (2010, thanks to the ramps created by Michael Petty - Canyon Lake, CA, U.S.A.). The parameters were re-computed in 2012 using a more accurate physical model compared to the 3.6 CMT version.
Norma Professional finest artist’s oil colors by Schmincke (21 bases) (2015, thanks to the ramps and measurements done by Angelo Paladini, Tarquinia, Italy)
Van Gogh oil colors by Royal Talens (25 bases) (2016, thanks to the ramps and measurements done by Angelo Paladini, Tarquinia, Italy)
ideal primaries (2010): this is not a commercial brand and is not based on pigments. It is an ideal opaque paint set with bases having uniform coloring strength over the whole visible spectrum and all the bases have exactly the same strength. This set is useful to check some mixing effects to see if they are due to subtractive mixing alone or to non-linear pigment propriety. For example, white (V=10) mixed with black (V=0) in equal amounts gives a gray with V=5 and uniform spectrum. Each masstone has 0 or 1 reflectance value on the whole visible spectrum.
The system includes also 55 reflectance spectrum databases:
Acrylic Studio Colours by Vallejoeasurements done onmasstone by Christian Skeel (Copenhagen, Denmark)
Aeroflash by Holbein - measurements done on hand made samples by Holbein, but the paint is not completely opaque (for this reason, the Munsell values calculated by rs2color do not always correspond to the ones reported on the paint labels, even if the error is limited)
Amsterdam Oils by Talens- measurements done on masstone by Angelo Paladini (Rome, Italy)
Artisan by Winsor&Newton - measurements done on masstone
Artists' Oils by Winsor&Newton- measurements done on masstone by Angelo Paladini (Rome, Italy)
Atelier Interactive by Chroma - measurements done on masstone
Bizancio Oils by Titan - measurements done on masstone by Angelo Paladini (Rome, Italy)
Kremer historical pigment database - measurements done by Anna M. Gueli (PH3DRA Laboratory, University of Catania, Italy)
“Modern Water Color Pigments” by J. Scott Taylor M. A.– measurements done by Dario Benedetti, MichelaPasquali, Nicola Rodella (Archaeometry Research Centre, University of Brescia, Italy)
Munsell Glossy 5B - spectra of all chips of this sector in the "Munsell Book of Color, Glossy Edition" (There is a slight color shift of the blues due to a calibration problem of my spectrophotometer)
Munsell Glossy 5G - spectra of all chips of this sector in the "Munsell Book of Color, Glossy Edition"
Munsell Glossy 5P - spectra of all chips of this sector in the "Munsell Book of Color, Glossy Edition"
Munsell Glossy 5R - spectra of all chips of this sector in the "Munsell Book of Color, Glossy Edition"
Munsell Glossy 5Y - spectra of all chips of this sector in the "Munsell Book of Color, Glossy Edition"
Munsell Glossy Neutrals - 9 spectra (N9-N1) at 0 chroma of the "Munsell Book of Color, Glossy Edition"
pigments: measurements done on masstone by mixing pigments with acrylic medium and measurements done on samples using mixed paint with 50% titanium white are also included. Commercial paint data is also included.
supports/grounds- measurements done on card/paper and canvas
whites: measurements done on masstone of various commercially sold whites

A warm thank you to my good friend Erika Bakos for translating these pages!
Web version:
The online version of color2drop, called PaintMaker, on the site Sensual logic was created by Christian Skeel. This version uses the current version of color2drop as a server. Therefore, all bases are available. PaintMaker has also a color picker. The website includes many painting tools and colors extracted from famous masterpieces.
The mobile version is for iOS, both for iPhone and iPad using iOS 9.0 or later, and has a limited number of paint bases included. It is called Real Paint mixing tools (RealPaint) and was created by AI4res. This version has a much more precise Munsell coordinate converter (for example close to the gray axis) compared to CMT and also coordinates of many more color spaces. It can load images, has a color picker to select the colors and has an auto-desaturation function to fit the whole image into the color gamut of the selected Paint Set. RealPaint can be set to mix colors using various Mixing Strategies, like "no Black used", "Black and White + 2 colors" and so on.
