Hey all, I am wondering if there are color charts available somewhere. I am hoping to find some stock type color charts somewhere so I dont have to make them. I need to figure out the grey scale value of individual colors and the colors ranges. In other words if I create a page with 50 colored blocks on it. Then convert it to a grayscale. I need to know what the grey scale value of that particular color would be in a percentage of grey. Dose anyone know if something like this is available for a huge variation of colors. Basically I need like color chart sheets type of thing. Could be based on pantone color book. See example below. If I changed the color part of the image to grey scale I need to read the percentage value when it is in grey scale. Any help would be great Thanks Bill B

Wow. Bit confusing this. A colour bitmap has no greyscale, but its relative luminosity can be measured. Converting colour to greyscale is not an exact science. Desaturation is the obvious method, but for instance, if you desaturate or convert to grayscale a RGB image, it will be different to a CMYK one. The only accurate way of doing it is to covert your source colour to grayscale, and then use the eye dropper and read the info palette for the resulting % mix. Hope this helps. May I ask WHY???!!!
