So i have an order for a flaxen chestnut with tack and a rider, is there any way to change a chestnut or something similar to a flaxen without changing the color of the tack and rider? I don't usually do color change

Do you have PS?

I do not, I work with GIMP :/

I have a pdf file of a tutorial but I'm not sure if I'm allowed to share it? :( I'll have to ask a mod or someone. <3

I can help!

Just let me type

EDIT:

To color change just the horse, you will need to use something called the "free select" tool. The icon looks like a little lasso and you can find it under Tools>Selection Tools on the Menu bar

What you will do is select all of the horse, even the tack. Once you have selected the entire horse, in the "Tool Options tab/window (this is also where you would change the size/opacity of an eraser or brush you're using. the icon looks sort of like a little TV) you are going to change your selection options from Add to Subtract. There will be little icons in the window right above checkboxes that are for Feathering and such (dont worry about those for now, but i can help you with that later if you'd like) so hover over those icons until you find "subtract from selection" and then you are going to select the tack that's on the horse. Depending on the amount of tack, you will have to click on the Free Select tool quite a few times to select all the tack.
