42ms Connectadets using a black background

In practice, the colour of the 42ms Connectadet is White, so when using a white background in SP, they appear as Black so they can be seen.

However when using a black background the 42ms Connectadets are a dark purple and are very hard to see.

Would it make more sense to have them appear white on a black background?

Also the Yellow 17ms Connectadets are easy to see on a black background, but very hard to see on a white background.

Would it be possible to make them a darker yellow so they are easier to see?
