Low contrast on Iceberg validation message

Example found on a create page.

There is not enough contrast between the "Ok" text and its white background.

Contrast should be at least 4.5 to satisfy WCAG 2.1 AA SC 1.4.3: https://www.w3.org/WAI/WCAG21/Understanding/contrast-minimum.html .

On this forum post, the use is reversed (white on green instead of green on white), but the issue is similar.

There are two possible ways to solve this:

• deem that the color used is semantically inappropriate and change it to another text color that passes contrast limits.
• deem that the color is semantically correct, and change its value to increase the contrast on white (same value as the one chosen in the forum post above is a correct solution)
