| * '''Luminance:''' Uses Unity internal Luminance function ( Dot product between color value and unity_ColorSpaceLuminance)
| |
| * '''Natural Classic:''' Dot product between color value and vector 0.299,0.587,0.114
| |
| * '''Old School:''' Calculates color average value ( sums all channels and divide by 3 )
