Why in the stat section of HeartGold, are the stats colored red and blue?

Question

The attack is colored red and the defence blue

Answer 1

The colors are related to your Nature. They are an aid to show which stat gets raised and which gets lowered. Red means the stat is raised, while blue means the stat is lowered.

They started it in HG/SS and do the same in Black/White too.

This is a little confusing because red usually means danger or bad. I remember it as red=hot, blue=cold.

Comments

also doesn't help people like me who have slight color blindness.  i can't see the red one ever.

Yeah the colours are very faint. I too have a little difficulty seeing the red one.
