ZiT V1.0:
Rainb0w_M0rph for ZiT. I've found best results by giving a brief description(eg, photo of a Rainb0w_M0rph cat), followed by a more detailed description of the scene you want(the cat has Rainb0w_M0rph fur, it's singing, and farting Rainb0w_M0rph as it flies through space).
Flux V1.0:
Rainb0w M0rph for Flux 1 Dev- my first foray into Flux loras, so let's see how this goes!
I'm noticing that when it works it works really well(IMHO!), and when it doesn't work, its just a good, but non-rainbow, image - putting the strength up does fix that without impacting the quality. I found up between 1 and 1.75 works just fine. Higher strengths work fine as well, but I wouldn't recommend going above 2.
XL V1.0:
This lora adds colour to the world, by adding rainbows wherever you want them. "Rainb0w M0rph" is the main trigger, but focus it by adding "rainb0w"(e.g., rainb0w cat, rainb0w skin) to any particular item that to want to pop!
It really doesn't like colourful ears on people, so play with the prompting if you have someone that forgot to paint their ears.
Trained on base SD XL.
Doesn't seem to have any affect on Pony models, but YMMV, of course.
Pony V1.0
Pony version! This one can be much brighter, but will also sometimes struggle to colour landscapes, particularly under low weights. It does well at human made objects, can do nice trees and plants, and of course, it can make colourful people and animals(and inbetweens) too.
The trigger is the same as for the XL version, "Rainb0w M0rph". If you have a particular area that you want to colour rainbow-style, you can also use "Rainb0w ...", where ... is whatever you want to focus on, such as "Rainb0w cat", or "Rainb0w hat".
If you find that your you Rainb0w cat is looking a bit dull, or is bright, but only in one or two colours, then try adding prompts such as "Rainb0w fur" or "Rainb0w tail", to give it a colourful kick up the posterior!
I recommend a strength of 1 to 1.25, generally. Any higher gets messy, 0.5 and below doesn't have much impact at all. I found it works pretty well with the original Pony; it has good effects on other Pony models too, including those aimed for realism, although more prompting tends to be required to get a full rainb0w skin there.
