The viewport axes/grid are the local CPlane axes/grid, not the global ones.
I see but it’s the planes XY, YZ and XZ.
Can I somehow match the colors?
Nope - it’s the planes LOCAL XY in all three cases…
I must disagree because if you activate one viewport (say FRONT).
and you start entering coordinates, you you enter Z coordinate it will create the point Up and not stay on place as it would be if it was the LOCAL XY.
Scrap that. I am wrong. This is very weird. I can’t believe I never noticed that before. One should be very careful which viewport is active when entering coordinates.
Yep, Rhino has been this way since day one… If you want to force world coordinate entry no matter what viewport is active, type a “w” in front, as in w0,0,0.
Usually I enter distances when working with viewports and the direction is determined by the mouse. This is why I have never noticed this before.
