What is the best way to replace color with a specific color?
I tried (Image > Adustments > Replace Color > Select Color with color dropper+ > Select Hex / rgb replacement color.
I would like the final result to look solid like the cad below.
If I understand correctly, the result you're looking for would be this?
It was pretty simple using Photoshop actually. At first I attempted using the color replacement tool. After five minutes experimenting with that tool, I decided good old fashion masking would be the easiest way to go.
One solution is to create a mask for each color you want
Using your Magic wand tool, configure the tolerance and pick a sample size of more than a point sample, and youll get a selection to nearly where you want it.
Create a new solid color, and photoshop should create the mask along with it based on your selection. Change the feathering on your mask in order to blur it to match the pattern.
Create another solid color underneath it, this one will be unmasked, and your base color.
In GIMP I know there is a single button for this operation, but in photoshop its a bit more complex.
That rug is basically 1-color + grayscale, so that helps simplify the process.
