Edit Question
Title
Body
I am trying to use this to figure out if a color is light or dark Evaluate whether a HEX value is dark or light Now. It takes in a int float calcLuminance(int rgb) { int r = (rgb & 0xff0000) >> 16; int g = (rgb & 0xff00) >> 8; int b = (rgb & 0xff); return (r*0.299f + g*0.587f + b*0.114f) / 256; } I have a hex color though. I tried to do this var color = System.Drawing.ColorTranslator.FromHtml("#FFFFFF"); int rgb = color.R + color.G + color.B; var a = calcLuminance(rgb); I got 0.11725 I thought it would have to be in the range of 0-256 or something like that. What am I doing wrong? Do I have to covert R to an int ? Or am I just way off?
