Affecting Undead

[Quishadi]

I have a series of questions regarding the Sorcerer Undead Bloodline, specifically the in-game ramifications of its Bloodline Arcana:

• What affect can color spray have on a humanoid corporal undead when cast by a Sorcerer with the Undead Bloodline?
• Does the first sentence of the Bloodline Arcana (Some undead are susceptible to your mind-affecting spells) specify an absolute limit or only an example?
• Or is the second sentence of the Bloodline Arcana (Corporeal undead that were once humanoids are treated as humanoids for the purposes of determining which spells affect them) really as wide open as it sounds?
• If the first sentence does describe the only way in which the rules change for this bloodline, then what of spells like color spray that are mind-affecting, but whose effects on the mind are phrased in terms of other in-game key words (in this case stun, blind and unconscious)?

Sorcerer, Undead Bloodline, Bloodline Arcana:

Some undead are susceptible to your mind-affecting spells. Corporeal undead that were once humanoids are treated as humanoids for the purposes of determining which spells affect them.

Creature Type Undead:

...

• Immunity to all mind-affecting effects (charms, compulsions, morale effects, patterns, and phantasms).
• Immunity to bleed, death effects, disease, paralysis, poison, sleep effects, and stunning.

...

Color Spray Spell:

A vivid cone of clashing colors springs forth from your hand, causing creatures to become stunned, perhaps also blinded, and possibly knocking them unconscious. Each creature within the cone is affected according to its HD.

2 HD or less: The creature is unconscious, blinded, and stunned for 2d4 rounds, then blinded and stunned for 1d4 rounds, and then stunned for 1 round. (Only living creatures are knocked unconscious.)

3 or 4 HD: The creature is blinded and stunned for 1d4 rounds, then stunned for 1 round.

5 or more HD: The creature is stunned for 1 round.

Sightless creatures are not affected by color spray.

My first impression is that stunning is separate immunity for Undeads than immunity to mind-affecting effects and unconsciousness specifically only affects living creatures so it seems that by RAW Undead-bloodline Sorcerer's color spray only effect on Undeads would be blindness.
