Edge & Firefox graph colors not distinguishable from each other on Interop dashboard with certain color deficiencies

[nt1m]

We received this feedback on the Interop 2024 dashboard. I did ensure the colors were color deficient friendly in 2023 using the Firefox color simulator in the A11Y inspector, which I greatly recommend for this.

Though finding contrasting colors for 5 different lines will likely be tricky (4 was very hard last year when I did it), and I think we should probably consider shapes to differenciate rather than trying to find new colors.
