Title: Help! GraphicsGale is mucking up my color selection?
Post by: Fizzick on October 19, 2013, 08:44:34 pm

Just about every time I pick a color in graphicsgale and put it on the canvas, the actual color value of what is on the canvas is very different from the color value I pick.

For example, I tried to lay down a rectangle of red with HSL 0, 70, 12- but when I color pick the rectangle, it is actually 354, 67, 13.
Is there a setting I'm missing?  ???

Transparencies can mess everything up. Turn off transparencies on your layers. If the alpha channel is on, Edit > Copy Display Image and repaste the image on your canvas, then delete the alpha channel by Image > Delete Alpha Channel

Code: [Select]


  0, 70, 12
354, 67, 13
Hue is circular so that 0 = 360.
Colour values are almost certainly stored in RGB. Converting between integer RGB and interger HSL/HSV results in a loss of accuracy.
If you want perfectly accurate colour values then work in the native stored colour space: RGB.
