Dunno if this quite fits with the challenge, as it's toothpaste and nor a rainbow
I dont think using my edit in the gallery would be allowed, because I think that would be considered a collaberation which Im not sure is allowed in the gallery (though maybe the rules changed). But in any case my edit is actually kind of messy. Especially the highlights which I just scribbled in at 2x. Feel free to use it as a reference though to improve the peice yourself, which will be a better help for you than just using mine.
Purple works well for shadings in first edit, but don't know about the second, assuming this is for the weekly challenge where 4 colours is max.
R1K, thanks for your help, your editing was amazing, I'm beginner, I dont know so much how to handle with palette, contrasted, texture and other things. Thank you so much! I have an idiot question, I can replace my pixel art by your edit? (I know it's really stupid, because your edit is by your own and that would be plagiarism), but is that people always help beginners like me editing and showing - and that's what I think it's cooler in the pixel-joint - so i always wonder this (srry for the bad english)
heres my thoughts on the pallete, I did 2 edits:

1. I noticed the blue in the tooth past is pretty similar to the green background and isnt being used much so I replaced it with the background color and added a color somewhat between the background color and purple to add shadows.
2. I replaced the new color with the purple and used the extra color to add highlights instead.
I like it but the purple seems too strong, so it messes with the subtle shading of the tube, making the style of the tube and tooth paste seem somewhat conflicting.
rainbow flavored toothpaste.
there, now it fits.
