@Tirjasdyn, I agree that the color combination is hard on the eye. mainly because both colors basically have the same hue(base color).
all colors in the editor have above 7 contrast ratio, which is the web standard. but because other colors are warmer, they stand out better.
We are basically experimenting with going darker in the editor.(as dark as the navbar) Please see the following screenshot and let me know what you think. Thank you for your feedback.
