Source: R/mixcolor.R
mixRGB.Rd

Vectorized additive mixing of colors in RGB space.

Usage

mixRGB(c1, c2, output = c("hex", "rgb"))

Arguments

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.

Value

a vector of hex codes or an rgb matrix

Examples

# 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)
par(bg = "black")

# plot input color vectors
plot(seq(255),
    y = rep(2, 255), col = a, pch = 15, ylim = c(0, 3),
    bg = "black"
)
points(seq(255), y = rep(1.5, 255), col = b, pch = 15)
# plot mixture
points(seq(255), y = rep(1, 255), col = x, pch = 15)
