Hard to see Selections in Bloom

The background for workspace for Bloom is a light grey. The selection color for a Relationship is a slightly different light grey which is very subtle and hard to see, especially if there is many of them.

Similarly Node selection is a hard to see but not as hard: it's a white but it can be hard to distinguish.

It would be nice to make these adjustable options, especial for those who are somewhat visually impaired.

Thanks for your feedback!
