Tools to assist with VS theming
Can be used to remap all color references in a .vstheme file. This allows you to find what element might need to change in a Visual Studio theme. (After taking a screenshot of course and grabbing the hex color of the element you are interested in)
For example:
<Color Name="ComboBoxListItemBorderHover">
<Background Type="CT_RAW" Source="FF7F6AAA" />
</Color>
