# 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` or **GetHexColorsFromImage** to get a `List` (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.*
