Describe the bug
Grey used in 'Section' block is different to the grey in the 'Links with Items' block

To Reproduce
Steps to reproduce the behaviour:

1. Add a page using the "component template "
2. Add a Section and set the background to grey
3. Add a "Links with icons" block and set the backgound to grey
4. See error

Expect the grey to be the same color, not sure which one.
As a work around i set the "Links with icons" block to color none, which did the job.
