Hey all. I am trying to edit a button color on a plugin and the config says:

"ButtonsColor": "1 1.5 1 0.5",
"LootAllColor": "0 0.7 0 0.5",

What format is that color in? Is that a format that is exclusive to Unity? If I could get the color format that its in, Im sure I could figure out the rest.
Thanks in advance!
