How to stop Roll20 from changing colors of my maps?

After I put map on page colors changing to sorta grey dirt. Any advice?

Check to see if a default tint is being added to your maps. Double click on the image and look for a tint. Change it to transparent if any has been added. If that is happening to all graphics, it may be that you have set a default tint to all graphics on your campaign settings page. If this is the case, you will need dev assistance to unset it, due to a long-standing bug. The address is <a href="mailto:team@roll20.net" rel="nofollow">team@roll20.net</a>.

@keithcurtis Thank you for quick reply. I've fiddle a bit around and found out that when I turn on Token Vision in Dynamic Lighting colors go back to map and it looks as it should.&nbsp;
