Is there a program in the market that are able to calculate all unique colors in an image file? ColorThink Pro does not do it correctly. I tried with Bruce Linblooms 16 million RGB file and it only showed 250 000 colors as a result. I can understand if ColorThink will not show all as the column with all number will be too large, but I wish I could see the number without using the color list, perhaps a future function?. Is there another way? I want to try to see how much the quantization error is when converting an 8 bit RGB file to Lab and then back to RGB. ColorThink is not able to show this.
