Alright, I figured I would see if those with more experience then me can help with a small issue.

I decided on a lark to recreate the dungeon from Swords and Serpents (nes). If you haven't heard of it I wouldnt be surprised, but if you have then well

I did as well as I could with the editor, though inaccurate in some locations, it is mostly just a little side project... the problem is however, the only way to get that rich of a blue, it makes everything blue.

Including the enemies. Now granted I am trying to kinda bring back an old game, so each floor bieng a pallete swap would be okay with me, but it hard to see blue spiders in a blue dungeon. I tried messing with emittance and different spell effects to see if they would clear up the situation a bit, and I couldnt find anything.

Any ideas?

TThanks for any and assistance.

You didn't tell us what you did to make stuff blue, but I have a feeling I know the answer you're looking for.
What you'll need to do is the following, and it will be tedious to say the least.
1) Download NifSkope and gIMP and a BSA extractor
2) extract all the meshes and textures
3) look in the CK to find the name of each mesh that you want to blue-ify
4) look at those meshes in nifskope and find the NiTriShape, and under that the BSShader node, and under that the name of the exact texture you need to edit
5) Go into gIMP (once you have the .dds extension plugin for gIMP) and open up the image. Make it blue-er by adjusting the color.
6) export the new image into Data/Textures/YourModName/ as a .dds. Make sure to keep the mipmaps, whatever the hell those are. They seem to be important.
7) Go back into the CK and duplicate the pieces you wanted to make bluer by renaming them. At the same time go into their mesh, and there will be a bunch of little entries below the mesh. That is where you will apply your custom texture. Do that and create a new form.
8) Highlight one of the pieces you want to replace with the blue version. Press CTRL+F. Now check the box that says "in entire cell" and hit enter.

Voila.

Hm, well I suppose that would indeed work. Granted my blue-ifying method was just to change the lighting to be honest. As I said, this was something I decided to do on a lark, not sure if I will go through all this... Or maybe I will.

Thanks for the advice, at the very least because I do enjoy retexturing stuff and wasn't cogniscent that there was a dds plugin for gimp, and also because I may do as you suggest and actually make the textures blue( and purple, and red, and so on for each progressive floor)
We shall see

there's also plugins for photoshop, dl on nvidia site
