[Chimera-users] about select and label a residul with another different from the color of the whole model

[Elaine Meng]

Dear Lei Zhang,
You are putting spaces in the wrong places.  Your first try probably had one space after the comma, giving message color is undefined.  Your second try needs to have a space after the lr and before #0.

Type exactly like this and it will work:

color red,lr #0:500

There are only two spaces.  One space is after “color” and the other space is before “#”

Also as mentioned in my previous message, another way is to select the residue and then use the menu to color only its label.

I hope this helps,
Elaine

Therefore, I defined the red color by command "colordef red 1 0 0" and "colordef transparent_red 1 0 0". When I carried out the command "color red,lr#0:500", there was a chimera error "mangled atom specifier". The color of the label can not be changed. I didn't know why. However, the color dialog can work very well. Thanks a lot!

You can also color ribbons, surfaces, etc. separately from the atoms.  This is explained in the “color” help page:
