Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Genete (genete) Assigned to: Nobody/Anonymous (nobody) Summary: Color dialog and RGB composite values don't show same values Initial Comment: The color dialog shows three sliders from 0 to 100. If I convert a Color parameter into its RGB components (composite) they don't show the same values. For example RGB = 0.5, 0.5, 0.5 in the color dialog then the composite RGB values gives RGB = 0.217638, 0.217638, 0.217638. Also the HTML code (I guess hexadecimal value for RGBA in a 00 -- FF range) correspond to the RGB values for the composited ones and not for the decimal numerical values of the color dialog. Reading about RGB in Wikipedia I see that there is a non linear correspondence between the diplayed color by the computer and the RGB values then there is a non linearity due to gamma correction. See: http://en.wikipedia.org/wiki/RGB_color_model#Nonlinearity But if it is in that way, it is confusing if you are using the composited values to fine tuning the color. Maybe it is not a bug, but it is confusing that color dialog and composited RGB values don't show the same values.
