I’m trying to draw and create my own Superman suit and I want to use these logos for inspiration. May someone tell me what suits and comics these logos appeared on so I can have a better look? Thanks in advance!

On my custom Superman, the blue on the legs doesn’t match the blue on the torso. I’ve checked on multiple sites and they all confirm that the blue are the same colours. Can someone suggest any improvements and why this has happened? Thanks in advance!
