The Monochromes

[BlueLatios]

I did some wondering, and I see what would cause problems/confusion.





These ones to me are very close or are monochrome:











I'd put these into closely monochrome (including most of my creatures in the sheet):



(Body looks grayish)


(orange body, yellow mane)


(spots seems a bit off, not too noticeable)


(horn)

(bigger spots)


(Dark purple body, red scales. Not too noticeable)


(Gray body, dark blue mane)






While some others I'd consider weakly monochrome or consist of more than one dominating color:



belly is blue, and the scales are black, both different from the wings, it's mostly due to the belly.


(green and orange/blueish)


(it's gray and white, but the cyan horns stand out)





(basically spots so large it seems like it has 2 colors)


(same case)






With these in mind, should I probably make monochrome levels for each creature and add them accordingly, or the levels aren't necessary and I add the creatures that are monochrome and look close to one?
