Weird Arcana - Curse of Chromatic Nullification (New Spell)

My inspiration for this new dweomer was the Bleaching of Golarion's gnomes and, as usual, the goal to strive for the strange and the bizarre: a spell that removes color both physically and metaphorically sounds pretty weird for me.

Curse of Chromatic Nullification

Enchantment

Level: Sorcerer/Wizard 3
Components: V, S
Casting Time: 1 standard action

Range: Touch
Target: Creature touched

Duration: Permanent
Saving Throw: Will negates
Spell Resistance: Yes

You drain all vivacity, emotions and feelings from the target with this strange dweomer. The target becomes immune to any effects that depend on emotions, like fear and morale bonus, including class features like rage. Consumed by ennui, the target suffers a –4 penalty on all his social checks. The total lack of commitment also changes the target's alignment to True Neutral while the curse remains.
Finally, as a side effect the target loses all color. His clothes, hair, eyes and even skin turn to shades of gray.
Golarion's gnomes are especially vulnerable to this curse, suffering 1 point of Constitution drain per day (no saving throw) and a 25% miss chance to every action attempted due to an overwhelming apathy.
The curse bestowed by this spell cannot be dispelled, but it can be removed with a break enchantment, limited wish, miracle, remove curse, or wish spell.
Bestow curse counters remove curse.
