Note: Information-bearing graphics and graphic control elements as well as their states should have a contrast of at least 3:1 to adjacent colors.

Personal Space

• The edges of the "Search folder" input field and the button for deleting search entries do not meet the contrast requirements for graphical control elements.

• Adjust contrast for switches (if necessary)

Note: If the two switches are not native elements, the contrasts should be adjusted accordingly. Only native switches
are an exception.

Spaces

• "Search folder" input field and the button for deleting search entries - See comment on Personal Space.

• "Search folder" text field does not have visible edges on purpose. Is that right
• x button is attached to the text. Text is fixed in [a11y] 11.1.4.3 Contrast (minimum) #4364

In terms of branding: by default the primary color and the bubble background color will be the same.

We'll address here the changes related to the toolbar mentioned in #4364:

Personal Space

• The labelling of the "Browse folder" input field does not meet the contrast requirements for texts, as the contrast ratio is only approx. 2.9:1.
  

Spaces

• The label of the "Search folder" input field does not meet the contrast requirements for text, as the contrast ratio is only approx. 2.9:1.

This one won't be addressed because switches are native elements
