For years I painted with the same palette. Warm and cool yellows, reds, blues, a neutral orange, dioxazine purple, burnt sienna and white. I have been drawn to limited palettes as of late, experimenting with ancient colors, etc. This led me to Geneve paints. I'm having a blast with them.
But here is my question, and it's genuine, not a "gotcha". Why does the Geneve website give the percentage formulas to mix tube colors, Paynes gray, Venetian red, Naples yellow, etc.? If the focus is on color matching what is observed from a photo or life what would be the need for mixing paint to match tube colors? I'm assuming it's just to demonstrate that these colors can be mixed. Is that correct? Is there another reason or purpose to trying to match a certain color from the 5 colors that you could buy already mixed?
Thanks in advance for an answer.
