Accessing Unity's saved palettes

Unity Engine
1

Hi All,

Hey I just noticed that if you save a palette in unity it gets stored in what looks like a scriptable object -

Just wondering, is there a way to access the colours stored within it?
Could be really handy!

Thanks!

You can set up a thing to figure out the type of whatever you’ve clicked:

public static class EditorCommands {

    [MenuItem("Commands/Get Type Of Selected")]
    public static void GetTypeOfSelected() {
        Debug.Log(Selection.activeObject?.GetType().Name);
    }
}

Using that, you’ll find that the type of a palette is a ColorPresetLibrary. Now, is that a type we can work with? There’s several ways you can do it, but if you have a code editor that’s competent, you can just search for the name and find a decompiled version of the type:

namespace UnityEditor
{
  internal class ColorPresetLibrary : PresetLibrary
   ...
}

Well, it’s internal, so we don’t have access to it from scripts. Time to just open the asset in a text editor and check what it looks like:

%YAML 1.1
%TAG !u! tag:unity3d.com,2011:
--- !u!114 &1
MonoBehaviour:
  m_ObjectHideFlags: 52
  m_PrefabParentObject: {fileID: 0}
  m_PrefabInternal: {fileID: 0}
  m_GameObject: {fileID: 0}
  m_Enabled: 1
  m_EditorHideFlags: 1
  m_Script: {fileID: 12323, guid: 0000000000000000e000000000000000, type: 0}
  m_Name: 
  m_EditorClassIdentifier: 
  m_Presets:
  - m_Name: 
    m_Color: {r: 1, g: 1, b: 1, a: 1}
  - m_Name: 
    m_Color: {r: 0.9705882, g: 0.007136685, b: 0.007136685, a: 1}
  - m_Name: 
    m_Color: {r: 0.13559689, g: 0.4712593, b: 0.5588235, a: 1}

Well, that’s easy to work with! I’d suggest just grabbing that text file, look for all lines starting with “m_Color”, and parse them into colors. It should be pretty straight-forward to create that as a helper-method. Give a call if you need more input.
