Blue mage for pathfinder!

[Wrequis]

I came across this blue mage class made for 3.5 and I want to use it in a pathfinder game coming up rather soon.

My DM has allowed me to use it for pathfinder, but he and I were wondering what sorts of changes one would make in order to keep it on par of the other classes adapted to pathfinder.

(ie; bonus feats, different class abilities?)

any input would be greatly appreciated!

Concentration, spot, and listen have changed. Remove concentration and add perception ( or just remove them but I kinda see how this class might have the perception skill)

Spell levels are based of the wizard and cleric lists. Or if not on their list have +1 spell level.

Add something minor that is color based on the dead levels 7/11/17/19 maybe...

Looking at the spells known for this blue mage class, it gradually becomes less spells known compared to that of a sorcerer.

At 5 x class level + int modifier; a level 20 blue mage would only have 100 spell levels(plus int) to choose from, which is roughly 2 spells known per spell level. I think this in itself can be very limiting, but to then add on a +1 spell level outside of those two spell lists can be even more detrimental to the class.

Any idea what sorts of 'colour based' abilities would be appropriate?
