This is a very simple tool to gather main colors of an image using Unity.
You will find a static class called ProminentColor. You can call GetColors32FromImage to get a List<Color32> or GetHexColorsFromImage to get a List<string> (of hex colors). Both of the methods will take these parameters:
| name | type | description |
|---|---|---|
texture |
Texture2D | Texture to get colors |
maxColorAmount |
int | The max length of the list to be returned |
colorLimiterPercentage |
float | Value used to compare color amounts. If color amount percentage is less than this value, it will not be marked as valid color |
toleranceUniteColors |
int | Value used to compare colors and unite them if is a match, useful to discard gradients |
minimiumColorPercentage |
float | Value used to remove colors that have lower amount percentage compared with full image |
simple result, without much fine tunning
If your image has borders, you will probably have this color in the list. If you wish to remove this border, there is a helper in ProminentColor class called RemoveBorder, it returns the Texture2D without the border. This method take these parameters:
| name | type | description |
|---|---|---|
texture |
Texture2D | Texture to remove the border |
compareColor |
Color32 | Color to be removed |
tolerance |
float | Tolerance to compare the color to be removed |
as you can see, there are small glitches, but white is not prominent anymore.
