This mod is now updated to work with The WItcher 3 v1.07+.

Version 1.04 is now fully compatible with "Color Blind Witcher Senses" (Under Options->Gameplay in The Witcher 3). Your customized colors will be used for interactables and quest objects, smell clouds will be the default "Colorblind Mode" blue. If you disable colorblind mode then the clouds will return to their original red color and your custom colors will remain active.

Version 1.03/1.04 is compatible with game version 1.07+, any version prior to 1.03 will not work with game version 1.07+
Additionally 1.03/1.04 WILL NOT WORK with any game version prior to 1.07
As of 1.03 this mod does not explode with "Colorblind Mode".

Created for some folks over at Reddit.com/witcher this mods usage is very simple:

1) Browse for the ROOT install of your Witcher 3 folder.
2) Type a color code in each of the boxes (e.g. #ff0033)
3) Enter an opacity for each color (between 0.0 and 1.0) where 1.0 is fully opaque.
4) Hit save

Features:
- Allows you to change the colors of both quest objects and interact-able objects.
- Allows you change the opacity of both quest objects and interact-able objects.
- Creates a backup of the modified Startup.bundle so you shouldn't risk any loss. Located in: The Witcher 3\content\content0\bundles
- Only conflicts with mods that serve this EXACT same purpose (changes a very specific file).
- Can now uninstall the mod via the UI resetting the game to it's default behavior.
- Works with colorblind mode (in game setting) allowing you to set your "smell clouds" to red or blue.
