Use conventional coloring for SIMD

Currently, we have a common color ramp we use for all our metrics.

The SIMD metric has a [well known tool](https://simd.scot/#/simd2020/BTTTFTT/9/-4.0000/55.9000/) which has its own color ramp.

If people have internalized that color ramp, we might potentially confuse them by showing different colors. In particular our blue means the opposite of the blue at https://simd.scot/#/simd2020/BTTTFTT/9/-4.0000/55.9000/

On the other hand, our existing color ramp is known to be designed as color-blind friendly.

This choice might also affect our thinking on #191

Find where the color ramp for metrics is defined in the codebase, likely in a visualization or styling module. Compare the existing color-blind friendly ramp with the SIMD tool's conventional colors. Implement a switch or override for the SIMD metric specifically, ensuring the change is isolated and doesn't break other visualizations. Test the new coloring in the UI to verify it matches the expected SIMD convention.
