I know how to change color with hue staturation but problem is different actually. I want to change the color into specific/individual color Let's say blue to yellow . But photoshop's hue/saturation system doesn't have something like that. Need your help
You could try creating a color range selection, then adjusting the hue or coloring. To create the color range selection, simply head into the "Select" menu, and choose "Color range". Once you're in the tool, simply click an area of the color you want to select. You may need to adjust the fuziness to get a clean selection. Once you have it, simply use the Hue/Saturation tool to tweak the hue or change the color.
select the colour area (various methods, magic wand, color range, saved selections + - x ) then fill with foreground colour of your choice that is ok if the colour is all one colour ie spot color, u might need to feather the selection
Ummm... you could make a selection, and then just fill it with the colour, but make sure you feather the selection. And then change the layer style to something that looks good.
