Hi my friend,
There is a small mistake you did which a lot of people do. When you "tick" the Color Overlay feature, you still see the "selected" feature.
If you want to see the options of the Color Overlay, click on the actual name and not just tick it.
Hope it helps,
Thank's for the Reply,
Well you see usually i would click on a solid object that i had copied over from illustrator such as a logo or even a scanned in line work, go to colour overlay it turning the layer to a solid colour that i have chosen or eye dropped but it's not working to the colour's that i choose (see pic, i have eye dropped white). I have no idea why this is happening, i have tried the same thing on other computers in my office and they work fine.
Thanks for your reply, yeah i usually click into the overlay option selecting the chosen colour of eye drop a colour in the graphic but for some reason it wont turn the layer into the colour that i have chosen, i've done in on CMYK, RGB and grey scale but still no luck, i have used other's computers where i work and they are all fine and doing what the function is supposed to do!
