I suspect this is typical of what is required (maybe not with the text?)

I am producing ternary radiometric images where potassium is shown in red,
thorium shown in green and uranium shown in blue. In geophysical maps, they
commonly have a triangular legend with potassium at the apex and the green
and blue at the lower points of the triangle. Hs anyone ever created a
triangular legend for an RGB image?
