My heat is on when dial turned to cold and blows cold turned to hot??

[jeepguy4276]

I put a heater core in it and had the dash out. Now my hvac dial is reversed. When you turn it left into blue it gets hot and if right to red gets cold. So I have hot and cold just fine but it doesn't match up to the control dial.

What did I mess up? Any ideas on a fix?

just repaint the blue to red and the red to blue... wish I knew im sure someone will chime in with a possible fix.
