Determine if a Colour is Light
Description
Internal helper function to determine whether a colour is light or dark
for appropriate font colour selection (black text on light backgrounds,
white text on dark backgrounds).
Usage
.is_light_colour(colour)
Arguments
colour
A colour specification (hex code, named colour, etc.)
Details
Uses standard luminance calculation: 0.299R + 0.587G + 0.114*B,
normalized to 0-1 scale. Coefficients reflect human eye sensitivity to
different colours (green > red > blue).
Value
Logical. TRUE if the colour is light (luminance > 0.5), FALSE if dark.
