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
Try the below:
using System.Drawing; Color myColor = Color.FromArgb(255, 181, 178); string hex = myColor.R.ToString("X2") + myColor.G.ToString("X2") + myColor.B.ToString("X2");
