OK, gathering up what we've got so far...
HD progression - as gold dragon
AC progression - as gold dragon
Size progression - as red dragon
Speed - as red dragon
Ability scores - as red dragon (we can modify as we wish)

The rainbow dragon is one of the most powerful of all evil-dragons. It is also the most beautiful, its hide displaying an everchanging display of iridescent hues of all colors. When the dragon is in bright desert light, this dazzling play of colors gleams so brightly that it is painful to the eyes, causing any attackers to attack at -2 to hit, or -4 in addition to penalties for fighting in the light if the attackers (like orcs or drow) are not accustomed to direct sunlight.

How about an ability like this:
Reflecting Scales (Ex): A rainbow dragon's scales are shiny enought to reflect light around it. Any creature within 5 feet + 10 feet per age category of the dragon must make a Reflex at their turn of be dazzled until your next turn; a successful save negates the dazzle condition. Creatures sensitive to light are blinded instead of dazzled, and a successful save makes them dazzled. Furthermore, they take a -4 penalty to the save.

The rainbow dragon usually fights with a claw/claw/bite routine. Five times per day, it can use its breath weapon of pure energy, which looks like a rainbow-hued blast of light. This weapon does damage equal to the dragon's hit points, but affects only one target per attack. The breath weapon is a 5'-wide beam of energy that extends for 100'. So bright is this light that if the dragon attacks at night, everyone within 100' of the beam must save vs. spells or be blinded for 1-4 rounds.
I'd like to avoid the single-target and stick to the more traditional line for this breath weapon. I agree with this dealing untyped hp damage. Should the blinding effect be limited to darkness, or also shadowy illumination?
For the secondary breath weapon, is everyone OK with a cone dealing multiple energy types? Should we leave off sonic, since it isn't associated with other chromatic dragons or prismatic spells, or include it like the rainbow blast spell?

In addition to-this, all rainbow dragons are capable of spell use. Very young and young stages of growth allow the rainbow dragon to acquire one first-level spell at each stage; at subadult and young-adult stages each, it may acquire a second-level spell. A third-level spell is gained at both the adult and old stages, and a fourth-level spell at both the very old and ancient stages. All rainbow dragons can speak and enjoy negotiating for ever-larger tributes and payoffs from cities that wish to keep such dragons from attacking them.

Following gold and red seems about right to me. Also, rather than the business about learning spells per age category, perhaps we should follow gold or red caster level progression as usual.
I like freyar's suggestion. Anyone opposed?

Rainbow dragons aggressively patrol their territories (especially in daytime) and prefer to attack when the sun is out so as to take advantage of their light-enhancing defenses. Rainbow dragons prefer brightly lit desert and plains regions, making their lairs in old ruins or caverns.
This all looks like flavor text.

The blood of these beasts can be used as ingredients in scroll ink for the spells color spray, prismatic sphere, prismatic spray, and prismatic wall. A bit of bone from a rainbow dragon is said to tip the best wands of conjuration.
We can add a little section on this.

Attacks based on elemental sources (earth, air, fire, and water) affect the rainbow dragon normally. Electrical attacks are taken with a - 1 hp/HD penalty to damage, which is helpful if the rainbow dragon fights a blue dragon for the same territory.
We've got several votes for the universal energy resistance suggestion. Anyone disagree? If we use it, should we leave off sonic, so it keeps a vulnerability? Do we want to set the resistance equal to age category (1 for wyrmling, 12 for great wyrm) or have it go up in increments of 5 like DR?

Oh, and for skills, I suggest Appraise, Bluff and Intimidate for class skills.
Intimidate is always a class skill for dragons. The other two sound good. Suggestions for the third?
For spell-like abilities: color spray, rainbow pattern, a few of the lesser prismatic spells?
