When placing a png in indesign the png changes/loses its original color. Ex. the very clear blue that I am using turns dark and "dirty". ( my RGB is : 5,125, 255 - when I type this I get a " out of gamut warning" a little yellow icon. When I click on it indesign automatically changes the RGB into: 67, 117, 187)
I have worked with indesign for 6 years and never experienced this before. I am guessing it has something to due with that the png is in RGB and indesign in cmyk, but I have no idea what to do about it?
Out of Gamut means the color cannot be printed in your current workspaces using CMYK inks. You would see a preview of the converted color if you move into Overprint Preview, use Proof Colors, or there is transparency and the blend space is set to CMYK.
If this is destined for screen use, then the color doesn't matter, but you should be sure the blend space is set to RGB.
