Hi,

Can anyone give me some ideas how to approach the problem that I've got with the blue on these trees (see attached thumbnail). Ideally I'd like to make these parts of the trees look similar to the rest (ie: brown!!). Ive been trying to isolate these parts and fix the colours all afternoon but no joy.

To sumup: How to replace the blue colours with a more natural bark colour? - Without affecting the other colours which are fine as is.

can be done better, but here goes.
ctrl + u brings up the hue/saturation shifter. for something like this that's what i'd use. instead of changing "master" select your blues, cyans and magentas individually and hue shift them until you get what you're after. may require a bit more work than my quick'un here.

One way that I like to do this kind of thing because it gives me so much more control is through Adjustment Layers.

The reason that I like to do this is I can use a mask on the adjustment layer to change just the problem areas and (if you use a tablet) its easy to lighten the stroke/opacity to blend the areas together.

try painting green on a layer set to colour.Huh? That really makes no sense as you can't paint on a layer set. It's just basically a folder for holding other layers. Anyways...


As usual, there are about twenty-three and a half ways you can do the same thing in Photoshop. One way to do it without changing the actual pixels is to make an adjustment layer. Choose the best one that will work for you and then play around with it. Sometimes you're going to have to use a bunch of different ones to get the effect you want, but right now you should only need one. As plaf said, Hue/Saturation would work well. I experimented with it and it worked quite nicely. I also played with a painted layer with the Blending mode set to Hue, but that didn't work all that great.

I think that in this case your best bet would be to work with Adjustment Layers to get the job done.

He didnīt mean a "layer set", but a layer set to blending mode "color".

Anyways, think "plaf" got a good solution, in my opinion you should stick with that.

Good luck

Thanks for the help guys, even with an adjustment layer is there a quick way that I only effect these particular blues in the image? Or am I going to have to painstakingly paint a layer mask for the areas I want to change?

Its my least favorite function in PS but you could use the replace color command. Maybe selective color can do it but it will take some work to find the component colors and remove them. Here is what I got after 10 seconds in replace color. I wasnt going for accuracy here either so there is some fringing.

Im assuming you want the halo to be gone? First of all youre using a really low res compressed jpg. So the quaity is shot right there. No photoshop tools is going to remove that successfully.
You might be able to pull some out using the wand, but I would create a mask and paint it out- its your best best guaranteed to work. Try to lose that "whats the easiest way to do..."
mentality. :P They certainly didnt say that while working on LOTR...hard work pays off.
