The IVs (to some extent) are listed at the IV bar.
Scrolling 3 reds mean 3 perfect IVs. More or less reads means more or less perfect IVs (depends on the amount of reds).
If the reds are static, it means those IVs are perfect. If blue, means those IVs are less than 31.
If blank, then those IVs are 0.
So the IVs that the bar doesn't really cater to, is 1-30.
(Would be a pain to assign a different color for 1 to 30)
They follow the order of HP, ATK, DEF, SATK, SDEF, SPE
