2D Sprite Colorize in three tones???

Hi every one!
I have question about сolorize texture using effects like tritone in after effects by tweaking shadows, midtones and highlights. This would help to diversify the game on the basis of a one texture or animated atlas.
See image! Is it possible to Unity?
PS. sorry for my english

 

sprite renderer -> color ?
and from script something like: GetComponent<SpriteRenderer>().color = Color.blue;

 

I was expecting so too, but experience has shown that in such a case I lose the highlights colors.
Possible that a C# is out to make, but the algorithm is more complicated than just appeal to the RGB channels.
Thank you for participating! =)
See image!

 

Actually we not should get SpriteRenderer>().color data. We should get the image pixels RGB channel data for subsequent modification! And the main question is whether it is possible in C#???

 

Not sure if these help, I'm only just beginning to look at shaders

I looked at the video tutorials on this link, but it unfortunately does not have a solution my question.
Any ideas on this subject?
Thank you in advance!

 

It is possible to get and set the pixels of a Texture2D asset in Unity via scripting. See the API in http://docs.unity3d.com/ScriptReference/Texture2D.html

There is a lot of color grading tools available in Asset Store. Unfortunately it seems that most of them are meant for real-time grading and not to bake results for a single texture/atlas offline. Some info here http://blogs.unity3d.com/2015/05/12/color-grading-with-unity-and-the-asset-store/

It is pretty easy to open an image into 3rd party editor like Photoshop and tweak the colors. After saving, the texture in Unity editor automatically reimports and you can immediately see the results.

 

Thank you Keely! Really useful links. I hope this will help our programmer.

Yes, this option is also considered. And on this subject I will create a new topic!
