[chimerax-users] inaccurate color box in the Models panel

[Daniel Larsson]

Attached are three screen dumps to illustrate the problem. The left side shows the initial state. Then I used the eye-dropper and clicked on 1. This resulted in the middle state. The RBG values at arrow-heads 1 and 2 are both (209,35,16) when checking the screen grabs in Photoshop. The model has however changed to a slightly darker shade. When I click on arrow-head 2 (no eye-dropper, just plain left-clicking), I get the right state. The RBG value at arrow-head 3 in Photoshop is (193,8,4). This seems to be the same color as the model has.

Regards,
Daniel

Hi all,

I'm trying to color multiple models in the same color using the color column in the Models panel. When I use the eye-droppper in the macOS colors panel, which pops up when I click on the color box, and then sample the middle of another color box, it gives me a slightly different RGB value. For example, if I start out with (209,35,16), what I get is (206,31,0). Another way of saying it is, if I sample the same color box with the eye-dropper repeatedly, the color changes. I can start out with a bright red color and then repeatedly sample the same box over and over and the color becomes a dark brown. What's up with this? Is it the macOS doing something with the colors of the boxes?

Related, is there a way of getting the current RGB color of a model (or all models)?

Thanks in advance!

Regards,
Daniel
