Old power customization files broken

[Monkeyking]

Did something change with the way the game handles saved power customization files? Old costumes and power customizations that I brought over from the original City of Heroes work fine. However, several power customizations that I saved back in 2019 now load in with "invalid" colors and default everything to a dark red color.

When you edit these in Notepad, the saved color values don't match the old/current color values that are normally used. Was the game saving power colors in a different format for a while there? Is there a way to get the game to go back to "rounding" these color values up to the closest valid color so I don't have to redo all of these again?
