Aus Intensität neue Farbe berechnen

[glkgereon]

also

CR = 100
HR = 10

CR = HR + (CR - HR) * FADE / 255

Fade = 0
CR = 10 + (100-10)*0/255 = 10 //Korrekt

Fade = 255
CR = 10 + (100-10)*255/255 = 10+ (100-10) = 100 //Korrekt


CR = (CR*Fade + HR*(255-Fade)) / 255;

Fade = 0
CR = (100*0 + 10*(255-0)) / 255 = 10*255/255 = 10 //Korrekt

Fade = 255
CR = (100*255 + 10*(255-255))/255 = 100*255/255 = 100 //Korrekt

beide korrekt?
