When I open grayscale images in Photoshop they have a cyan color cast to them. On an area that should be pure white the eye dropper registers

R: ED
G: FF
B: FF

in web color mode which gives you an idea of what the image looks like. CMYK are all 0% and K=0% in the grayscale slider but the image has a cyan color cast across all shades, not just the white, you can see it all across the color slider. These images display fine in a web browser with no cast, but if I print from photoshop they have that cyan cast.

I don’t believe this to be a monitor color profile problem due to the RGB eyedropper showing the cast in those values.

Another problem as a result, if I paste some of this work into an RGB image, it retains the cyan cast rather than being true grayscale.

I’ve never really learned about the color management and maybe this is what is causing the problem. Can anyone give me some help? I’d like a pure grayscale image with no color cast, not only when creating a new image but I’d like to be able to fix my existing images.

Hey Xany,

Attach an example to a post and I’ll take a look at it. You’ve got me curious too…
