[Kart]what does this mean?

[Obelisk]

hello, I'm making a mod for SRB2Kart, and I'm having trouble with the colors for the character, so...
"transparent_colors": [
115, 115, 255,
82, 82, 255
],what does this mean?

Big or small, any type of help is welcome.

That's kartmaker related.
Seems to be related to the non-transparent template you're using, and what colors to interpret as transparent when parsing the whole image.
The numbers are in the RGB format.

These two colors will be interpreted as transparent when kartmaker does its magic.
