What I have is R:255 G:181 B:178, and I am working in C# (for WP8, to be more specific)
I would like to convert this to a hex number to use as a color (to set the pixel
You can use ColorHelper library for this:
using ColorHelper; RGB rgb = new RGB(100, 0, 100); HEX hex = ColorConverter.RgbToHex(rgb);
