Unity Prominent Color
This is a very simple tool to gather main colors of an image using Unity.
How to use
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
Removing the white (or any color) border
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.
