This acrylic paint color mixing chart is based on the Lascaux Sirius drop system, using Lascaux Sirius Acryl acrylic paint applied to a white Acrylite extruded acrylic glass sheet surface. The color swatches are then are digitally photographed in 5000K daylight (Pantone D50), processed in sRGB colorspace, and white-balance color-corrected using a 50% Grey Card on a standard sRGB color gamut monitor.
Special thanks to artist Rob Duarte for use of the superhuge laser cutter, the machine with which we created the 1-inch square acrylic swatch bases.
This exercise was intended to help me learn how to make colors from single pigment paints using the smallest color palette possible. I likened it to “doing my scales” — a reference to piano lessons. Creating color swatches has turned out to be visually what musical scales are to the ear.
I’ve posted my results here for the benefit of the internet community because I haven’t been able to find a complete Lascaux Sirius drop system chart out there. (There are abridged pdfs from the manufacturer, but not a complete spectrum). Even if I now find one, this experience has been beneficial nonetheless — they call it artistic practice for a reason.
