April 13, 200718 yr Hi: On a Mac using Filemaker 8.5. I selected a fill color from the CMYK Sliders of: Cyan: 100 Magenta: 50 Yellow: 0 Black: 0 and applied it to a rectangle object. When i selected the object and checked the fill color the CMYK Sliders read: Cyan: 89 Magenta: 50 Yellow: 3 Black: 4. Why would it change like this?
April 13, 200718 yr Filemaker stores its colors as RGB, not CMYK. Apple color picker converts the values on-the-fly. There is no one-to-one mapping between these two color spaces, and several conversion algorithms are possible. In Apple's color picker, CMYK (100;50;0;0) converts to RGB (0;83;149) and this converts back as CMYK (89;50;3;4). Not really Filemaker related.
