Just adding my twopenneth worth here - I hope this hasn't been forgotten. It'd be a handy update to the tools offered to builders. I know rates for red/green colour blindness vary according to gender and ethnicity, but it's potentially anything up to 8% of your users. That's not allowing for other visual disorders and the other general problems pointed out which would be helped by looking at this again.

I'm red-green colorblind and I'm still relatively frustrated that such a fundamental feature hasn't been introduced yet. I really shouldn't have to focus extra hard on the gizmo just to figure out what I'm even looking at, or have to rotate the camera long enough to make it align with a background-color that offers enough contrast for me to see what I'm doing :/

This should be a totally natural and intuitive interaction.

As an update to my own post here, in the 18 months since making this request, my visual acuity has gotten worse. The green arrow (and especially the green resize dot) are all but invisible to me against lighter backgrounds. I have to turn off Highlight and jiggle the Ctrl key a few times to find the gizmo sometimes. I really just want to enjoy building in SL again.. been doing this for 19 years this month.

Definitely a need for this, I struggle and my eyesight is fine. I can't imagine the accessibility issue it causes for those with sight problems.

Merged in a post from Nadya Metaluna:

Title: dont use colors when building objects that humans can be colorblind too as a default

Details: imagine trying to move this colorblind. my arrow is not on it

Definitely a need for this. The arrows are often difficult to see on certain backgrounds even with normal color and contrast vision, let alone for those with colorblindness and other issues.

This is an excellent suggestion, I'm surprised it wasn't requested earlier.

Please at least give us an optional high contrast outline. The red, green, and blue can be difficult to see in some builds even without color vision issues.

It can also be difficult to tell when you are hovering over something like the move tool arrow because it only gets larger. If it had a high contrast outline that changed color when you hovered over the arrow to move (or square to resize) it would be a huge help.

Agreed. This is another accessibility issue that really ought to be addressed. I understand that SL wants new residents to join, but retention is key, and that includes retaining residents as their bodies rebel against them, be it by age or other causes of this type of issue.
