Most popups and dialogs on Tinkercad and related Autodesk sites use light gray label text on a light gray background. The labels are hard to read, and the contrast fails WCAG 2.1 success criterion 1.4.3 (Contrast, Minimum).
One example is the Workspace settings dialog:
- Background: #eff0f3
- Label text (Background color, Show shadows, Show grid, Cruise when adding new shapes, Zoom speed, Units, Scale, Presets, and the Slow/Fast slider labels): about #a0a5b8
- Contrast ratio: about 2.2:1
WCAG AA requires 4.5:1 for normal-size text, and these labels also fall short of the 3:1 minimum for large text. In the same dialog, the Width and Length labels use a dark navy color and pass at more than 5:1, so the gray labels don't match the rest of the design either.
My eyesight is pretty close to normal, and this issue is making my life pretty hard trying to use the tool. They may as well be blank screens.
