Photoshop and other professional graphics editing software offer a wide range of features to deal with color management, which include assigning a color profile to an image, interpreting embedded color profile within an image, and converting between different color profiles and color modes.
Photoshop uses predetermined default color profiles for different color modes, which can also be adjusted in the Color Settings, where you can select a color profile and other attributes for different color modes (or color models), e.g. RGB, CMYK, Gray.
Color profiles (or ICC profiles) describe the characteristics of color input and output devices by means of well defined conversions to/from a profile connection space (PCS), either CIELAB or CIEXYZ, which is then used as a common intermediate space for converting between two different color profiles.
The (den4b) Colors tool does not currently deal with color profiles. Conversions between different color spaces are performed using common linear remapping algorithms, i.e. simple maths. In contrast, conversions performed in Photoshop would use color space remapping according to the selected color profiles.
A conversion sequence using linear remapping algorithms:
RGB -> [linear remapping algorithm] -> CMYK
A conversion sequence using color profiles:
RGB -> [sRGB / IEC 61966-2-1:1999] -> LAB -> [Coated FOGRA39 / ISO 12647-2:2004] -> CMYK

]]>Thanks for the reply. All the very Best for on the ongoing project.
]]>Please provide more details, so we can investigate it:
What kind of monitor and desktop arrangement do you have?
What exactly is happening, or what you think should be happening? What does "go out-of-whack" mean?
Can you provide a screenshot of the problem?
Have you tried the latest development version?
Thanks
]]>A very interesting feature. I have added this to the list for implementation.
]]>I think "HTML", "Hex" and "R,G,B" will work for now and we can revisit this if we get some confused users down the road.
]]>The program is working great now.
