The accent color (for instance selected track or selected tool) and high contrast of the white fonts in C 10 are really hard on eyes.
Here is another thread from C10 General forum branch about it
Please make the accent color, font color and size customizable.
In Cubase 9.0 the accent color was grey and the fonts ware black, which was pleasant to look at.
And also please get rid of gradient in events - which is not compliant with overall flat design of C 10 and from the usability point of view was unnecessary before as well.
