Hiya ​@takpolecamxd - I just checked on this internally (I could also see the colors looking darker), and while I don’t have an exact date on a fix, I got confirmation that this is being tracked and worked on.

In the meantime, one suggestion I can offer is to use the color wheel to use one outside of the presets. If you have a hexcode you’d like to use, you can apply that to your arrows/connectors to be more precise.
