- c1, c2
Colors 1 and 2. Accepts vector of hex color codes or an rgb matrix
- output
either "hex" or "rgb". "hex" produces a vector of hex codes for color mixtures. "rgb" returns the rgb matrix.

# with black background
a <- GiottoVisuals::simple_palette_factory(c("green", "black"))(255)
b <- GiottoVisuals::simple_palette_factory(c("red", "black", "blue"))(255)
x <- mixRGB(a, b)
op <- par(no.readonly = TRUE)

)
points(seq(255), y = rep(1.5, 255), col = b, pch = 15)
# plot mixture
