[BUG] Text Contrast Enhanced

[KatiePUX]

Text was found to contrast with its background in a way that could be difficult for users with
a visual impairment to perceive.

Text was found to fail the enhanced text contrast requirements. This instance can be found
with the text found within the ‘send a survey’ component. The white text contrasts with the
background at a ratio of 4.7:1, which suffices the minimum text contrast requirements;
however exceeding this ratio allows more users, especially users with a visual impairment
that affects the perception of colour to read text on the page.

@KatiePUX I just noticed that this issue is around level AAA compliance.

It is my understanding that we are aiming for level AA compliance.

Therefore, I believe this issue should be closed.
