After some discussion, we feel that we should make sample data just a little more prominent for new users in 6.4. Ideally, we'd prefer a splash screen to guide a user in bit more explicitly (https://github.com/elastic/kibana/issues/18828) but since we do not have time before feature freeze, we've decided to make a few more tweaks to the homepage.

We plan to take this approach with the expectation that we'll have an vetted and approved splash screen from design implemented in an upcoming minor version.

Can I make a suggestion to change the highlight colour to use the Eui highlight colour? I think it makes them stand out a little more, without clashing with the telemetry callout.

I'm not sure that the using the same blue "clashes" with the telemetry banner, but I can see that it _could_ lessen the attention. However, I'm not sold on this yellow. It reminds me of bad highlighter days. I do like the separation of boxes and making sure the content is centered in each.
Here's a recommendation for switching the text to use the terms "Sample Data" and "Your Data"

I also prefer the blue, I think it actually stands out more than the yellow. I'll leave it to the design team to decide, just adding my 2 cents
