I am working on a banner for a startup to be displayed at events.

However, I am struggling with supporting colours at the moment.

The entire thing looks very dark, and I wonder if it does the job of drawing the audience in, or will it just be ignored by passers-by.

Any feedback on how I can alter the colour scheme to make it bright while keeping the main brand color of #191c4c? I feel like the man in the middle should be a bit brighter, but I'm not sure what alterations to make.
