Now that hazy. overcast skies are upon us, i'm getting curious about using the multiple exposure
mode of the camera to enhance color.
Anyone here tried it and gotten good results?

Do you mean the one they sometimes call HDR - where the camera takes several pictures and produces the best image it can? Sony has a similar setting. They have Auto and Auto Plus, or something like that. I don't use settings like that, but it sounds like a good subject for experimentation. What kind of a camera are you talking about?

If your talking about bracketing, and combining in HDR the answer is yes however I shoot in manual and bracket 1/3 -2/3 stops up to seven images.I sometimes don't use all seven images but they are there if I need them.

Page 210 of my D810 user's manual does not suggest it is HDR or bracketing but it is probably similar.

If you are talking about taking 2 or more shots then having the camera superimpose one upon the other - yes, I've tried it with mixed results. Be sure to read and understand your cameras' instructions.

Recently saw one comment on, I believe, UHH where the poster said he/she had good results with two exposures - one set for the dark area the other for the light area. This is NOT the only way to do multiples...

I shoot multiple exposures on my Nikons. Works best when the subject is lit and moving and the background is dark. I have seen one of the canons where you can see and align the second exposure over the first in the display screen on the back of the camera. With the nikons you are shooting blind for alignment. The 3-shot image below was shot with a 28-300 at 300, hand held from the back row of a theatre in Havana in 2014. There were two dancers. Should have pushed the ISO a bit more and suffered some noise for better sharpness. Also, this image was reduced and posted on Fb, and for this response I downloaded it to my phone and uploaded it for the reply. Probably not doing the image justice.

no, no, no, the question is not about multiple exposures or increasing the dynamic range by bracketing
the exposure; its specifically about enhancing the color.

You'll probably have more success producing artificial colours with post-processing software than in the camera.

i'm trying to avoid the artificial look that comes with increasing color saturation.

So you're trying to enhance the color, but not trying to enhance the color?

Check out page 210 of the download link i provided and tell me what you think they are up to.
Is it just a sneaky way to improve signal to noise ratio?

Have you heard about that someplace, or is it your own theory - how do you think that would enhance color? You might be able to experiment with different blending modes, but to do that you could just make a duplicate layer.

They suggest nothing about color any more than about HDR.

It is strictly about either summing data or averaging data. Summing will effectively increase the ISO. Averaging will effectively increase the SNR.

These are well known techniques that are much more useful when done with post processing external to the camera.

Well I sure missed that!

The only improvement in color would be due to the higher ISO.
