I'm giving up mainly cause I'm just to shit at finding good colors and everytime I think I found something good I either mess it up or the more I look at it the worse I get so I think I'm just done with it.
Try to use color theory application of 50/40/10 rule
Primary color 50, secondary 40 and accents 10. Where 50 is main most dark or most light color, 40 is secondary color complementing main one and 10 is accent opposite of main color and his compliment.
Examples:
Indigo - blue - light orange;
Black - grey - red;
White - green - black;
Light blue - grey - bordo;
