How do I solve the problem of inverted colors in OBS studio?

I tried to make a recording for gameplay of youtube and twitch but via obs but I found something very inconvenient. The colors are all inverted ... (or fading, I have no idea) I would like a help from you if possible Ubuntu I'm using is the 18.10 obs is the 21.0.1

Solution 1:

In your scene, highlight the vidio source and choose "Filters" from the menu.

Choose the filter marked "Color Correction". Inside the filter, slide the "Hue Shift" back and forth until the colors are correct.

Solution 2:

I tried the fix suggested in a comment by Erikcht and it corrected the problem of inverted colours:

Select the source and click on engine.

There will be a checkbox for change red to blue and changing this fixed the problem.
