faces turning blue

im modelling a low poly human, and i have just started modelling the legs. the legs have just suddenly become blue. i am in the solid view. PLEASE help.

start taking some deep breaths :smiley:

probably, you went into weight paint modeā€“just select object mode from the menu on the 3d view header :slight_smile:

Or also if you are in wire frame view in Edit mode the polys are blue transparent and become purple where faces overlap in the view port.
