Rhino 9’s icons are extremely difficult to read. I’m a colour blind person and the low contrast of the outlines is killing my eyes. 
I see far less colours than people with normal vision, so I mostly rely on a few basic colours and the contrast to distinguish the icons.
Will the developers offer the option to switch to the old contrasty look of the icons from Rhino 7? They were the perfect shade of blue with nice black outline for easier readability. This means:
- Nice saturated blue (don’t use washed out blue);
- Saturated other colours (no washed out colours that are diffigult to read by colour blind people);
- Don’t replace blue with yellow for the icons that were classic blue for years;
- Use solid black outlines.
I intend to buy Rhino 9 when it finished release gets official, but those low-contrast icons are a bad news for me…
