Background colour Defaulting to "Bright" instead of "Dark" when adding a image with transparent background

Hi!

I'm having some trouble with the section colour when I add an image with a transparent background. I add the image change the colour to dark and it will automatically show the "bright" even know "dark" is selected". It keeps defaulting to the "bright colour". When I add a new section, the backround colour is also "bright". 

I have a feeling it has to do with the theme, Myhra.  I can get this working on a different theme but I am stuck because I've already done a bunch of customizations.

Any ideas of what's going on? I tried changing the colour palettes to a default with no luck.

Screen shot of how the options appear in the "bright colour" instead of white.

THANK YOU.

Here is a demo of the gold coming in when it should be turquoise.

Im having the same issue, did you ever figure this out?
