Quick Color Change

This is the fastest method I know for changing the color of something in a picture using GIMPPortable, or Photoshop. You make a hasty selection with the lasso tool, feather it, and then adjust the hue, using the option to adjust only the blues in the picture. This prevents unwanted color changes simply.

Step 1 Make a Quick Selection

Open your picture in GIMP.

In my picture, I want the blue car to be green, but not the carpet, or anything in the background, so I need to roughly select the car.

Click on the lasso tool. Drag a quick selection around the car. Tweak the selection a bit using to add to the selection and to subtract from the selection. You do not have to be perfect with this. Not even close.

Great. Car selected.

You could use this techniqe for background subtraction on still images.

[royalestel]

How's that? I know of a few background subtraction techniques but one using a hue adjustment is news to me. Care to share?

[jinventive]

Or maybe I was wrong I tried it later and it didn't work. Sorry :D

nice to see how everbody uses your instructable for new instructables. but you can also download the normal version of gimp on www.gimp.org!!! it works alot faster!

[royalestel]

Who uses my instructables for new instructables? Anyhoo . . .I'm going to check out the new version of GIMP now.

his bag is not green

[ARVash]

hah, you misunderstand the effects of GI. or global illumination. If you look at the picture of the blue car, his bag is tinted blue thanks to the reflected light. He did this quite right, sorry asianwizard ;p.

You know, I didn't even notice the bounce light on the bag. Sharp eyes y'all!
