Help me convert these three 3.5 spells

[Optimistic Cynic]

Reading and asking around, it seems like most people believe that the Magic Item Compendium should be fine to use in PF, with the exceptions of the stat boosting abilities, and things that boost skills/powers that no longer exist. But the Spell Compendium should be gone over on a spell-by-spell basis with the GM.
Well, nobody in my group feels knowledgable enough to make such judgements. So I was hoping some of you might be able to help me with three spells that are an important part to my character...that do not seems to exist in PF (yet).
My character is a Wizard, who loves the random nature of the rainbow/prismatic spells. I used those spells all the time in 3.5. They were almost part of my character's personality. But we cannot find their equivalents in PF.
Those spells are Rainbow Beam, Rainbow Blast, and Prismatic Ray (the one that is like a weaker version of PF's Prismatic Spray).
Does anybody have any thoughts on those spells and if and what should be changed about them to make them PF compatible?
I can post the spells and their abilities if it doesn't break any kind of board rules to do so.
Thanks for any help that can be given!

You can not post the spells themselves. They are not Open Content.

In Pathfinder, the various effects of the colors of the Prismatic spells remain unchanged, except for the Green color. That should be the only conversion needed for Prismatic Ray.

Both Rainbow Beam and Rainbow Blast should work just fine as they are.

But he (or anyone else) can post a "fan conversion". It's legal as long as something in the wording is changed and the poster doesn't claim it as their own.

Thanks for the help! I'm not brave enought to tempt things and post paraphrased descriptions of the spells. I wonder, could I post links to webpages that describe them? Or should quick summaries and paraphrases work?

Anybody else think the spells should be good to go, with the Poison change made to the Prismatic Ray?

Rainbow Beam is certainly good to go.

Rainbow Blast looks like a pain in the ass to resolve, but nothing game-breaking, should be good to go.

Prismatic Ray just needs whatever changes PF gave to Prismatic Spray.

Okay, so without getting into specifics, this is what my 13th level character would be able to do with the Rainbow spells.

2nd level spell - Close range - Range Touch - at my level it would deal 4d12 damage of random energy type

3rd level spell - Medium Range - Line - at my level, it would deal 1d12 of each of the five energy types (so, 5d12 damage total, resistances applied seperately)

Do these seem about as powerful as PF spells of the same level being cast by a 13th level wizard?

Fireball is the iconic 3rd level spell. That would be 13d6 with an AoE attack. Does that match up well with a 5d12 Line of each energy type?

We have two votes for 'should be good to go'. Anybody else?

Thanks to everybody that has replied to the thread!

That's incorrect. Like the Spell Compendium there are a variety of responses including... "Not using any 3.5 leftovers in my Pathfinder at all." With the sheer breadth of spells provided from Core through Ultimate Combat, I no longer see the need for anything from 3.5. So anything from either book is on a case by case basis with me with "NO" being the default answer, unless I'm persuaded otherwise.

It's not that hard to undo most of the improvements that Pathfinder made to the game by allowing 3.5 supplemental material without a good deal of winnowing.

Sorry, just realized I said the Fireball would be 13d6. Should be 10d6, right?

Anyways, we are currently going to allow these three spells into the campaign. The power levels compare favorably to other spells of those levels (i.e. Beam vs. Scorching Ray; Blast vs. Fireball; Ray vs. Baleful Polymorph/Suffocation/Cloudkill).

Thanks to those who responded!
