'averaging out' the colour of a texture?

14 posts in this topic

Hi everyone,

 

I'm working with this water texture:

However, it doesn't look great when I tile it in-game, because of the fact that it has light and dark colour highlights across it, which are quite clearly visible when tiled.

 

Does anyone know how I could remove those light and dark differences and average out the blue colour, using GIMP or paint.net?

 

Thanks!

First thing, I would try making it grayscale to isolate the tonal differences without having to worry about color values, and use those filters and mess with the histogram. You can then go back and colorize is back to blue fairly trivially.

 

I would offer more specific advice but my laptop is waiting on a new AC adapter so I can't really experiment...

Prinz Eugn, that's just the hard way of using the curves tool I posted about above.

 

I don't think so, since the dark values and light values are also different hues, meaning you'll have to adjust each channel's histogram in order to get even color. Making it grayscale just removes that part of the equation so you're only dealing with absolute value, not juggling value and hue.

You just move the curve into a straight line on 'value mode'. Then you can adjust the rest by eye if you want to go deeper.

What software are you using? I'm using Photoshop, but I think GIMP would be the same. Manipulating the values will still you give you obvious differences of color when tiled, since the dark spots also have a different hue (as well as brightness value) from the other parts of the image.

Thanks Prinz Eugn - that's exactly what I was looking for. I did try it myself, but I couldn't get anything reasonable. I converted it to graysale in GIMP and then messed around with the curves and levels for a bit - I couldn't get an even colour. Would you mind telling me what tools you used? Thanks!

I'm using GIMP in this case, because Photoshop Elements 8 doesn't have a curves editor unfortunately. It's one of the few reasons I bother to even install GIMP.

When the curve editor is open, I use the color sampler / needle tool to click on the dark spot in the image, and that shows me where it is on the curve. Then I just move that point up or down until I even everything out.

There are many ways to go about this.
