Running CS, experimenting with the posterize command and under the help section it states:

"If you want a specific number of colors in your image, convert the image to grayscale and specify the number of levels you want. Then convert the image back to the previous color mode, and replace the various gray tones with the colors you want."

When I convert to grayscale I get a message saying “Discard color information” OK or cancel. It will not convert to grayscale unless you pick OK. There does not seem to be a way to get around that prompt when converting to grayscale. I’m converting it back by toggling on RGB color and all I get when I try to get color is shades of gray. Am I converting it back correctly? Any help appreciated!

I think the better effect is reached by not converting at all. Otherwise, I think you should "desaturate" instead of convert to Greyscale.

But again, to get that sixties Jefferson Airplane LP cover look, Just posterise to 3 or 4 levels, and crank up saturation even.

I’m new to Photoshop and I screenprint fine art. As I understand the only way to get a set number of colors with posterize is to convert to grayscale then the number of levels reflects the number of colors. I have tried desaturate and get the same results when trying to change color, I’m using “change color”. I’m able to change color before I convert just not after converted. With desaturate/posterize I change the color and have preview toggled on but it does not change the color. Is this the correct way to change color?
