Colors off in Ubuntu

[Helithumper]

The colors in my version seem to be off from the screenshots on github...
Upper Left is my screen, bottom right is a screenshot from the README.md of this repo

)

My background color: (38,43,55)
Screenshot background color: (32,39,52)

My Grey Text: (174,201,194)
Screenshot Grey Text: (217,215,203)

I am very unsure about why the colors would be off

None of those colors are correct. The correct background color should be (33, 39, 51) in sRGB.

Me too, I thought I was losing it. Background on screenshot for Mirage: (36, 43, 55). Background in ST3 3210 on Ubuntu 20.10: (31, 36, 48). Worse with Ayu Dark.
