Thumbnail design feedback needed for personal branding

[late gyro]

I made some new thumbnails, let me know which one is better for personal branding.

I heard that its better to have a fixed number of colours used for thumbnails in content creation. I've been working on my thumbnail creation and I'm stuck on having 2 or 3 colours for thumbnails. I wanna know if which one is the best looking one, I personally love the colour purple, so I'm thinking of having it for my branding.

I mean personally I wouldnt say one is alot better than the other. If I had to choose one it would be the red.
If we are going for the average viewer the red will likely have higher ctr and it has a more aesthetically pleasing colored background. Personally the colors on the right with purple feel a bit random.

The green background doesnt pair well with the blue or purple.

Yea the red one looks pretty good, maybe purple and green aren't that well suited together

Idk I'm trying to do something with my personal branding and make myself more recognisable

Purple is my favorite colour so I wanted to incorporate it into my thumbnails to give a unique impression to it.

This is persona right? I think the red looks better because it's already associated with the character. I think purple and green can look good together but not in this context.

Yepp, red is joker's signature, probably makes sense in this context
