Custom colors


I would like to ask how to change, replace or add extra colors for current standard ones?

The following is an extract from the old newsgroup where @pascal explains how to customise the color dialog. Its a good idea to save the default file as a back-up in case you want to return to the original and I’m not sure if your custom file will be over written during updates.

This extract is for V4, V5 has changed the file name from colors_1033.txt to colors.txt and you’ll find it in the support file:

Quote -

To define your own color palette, customize the
colors_.txt file in the Rhino Support folder.

(e.g. colors_1033.txt for English)

If the colors_.txt file contains more than one color
definition, the internal color list is replaced with the colors
extracted from this file.

The “;” or “//” characters can be used as comments either at the
beginning of a line or after the color definition.




End quote

I just tried this and here is a screenshot:

Hi Brian,

This is very good, thanks for your help.

I have another question to use the “real name” of the color except of “Other” appears on the panel. Or add some extra for the standard 8 colors (White, Black, Red, Yellow… Magenta). Can I add some extra colors for the standard ones?

Sorry, that’s beyond my knowledge, but I would not expect the drop-down menu to be user customised. Perhaps someone can confirm this.

Hi OnRender- currently the color list in the drop-down is fixed… you do not get to change it.


Thanks for your answer,

That would be great to be customizable, Color with Name can be another ID for the type of objects (independent from layer colors).

I would use them to identify Room types on hatch ( eg. Residential, Recreation, Lobby or anything).

Hi Brian,

I’m actually working with rhino 6 and I’n not finding the colors.txt file you mentioned.
Could you help me to find it out?

This is a seven year old thread… :grimacing:

The colors.txt file is located here in V6:

C:\Users\<your user name>\AppData\Roaming\McNeel\Rhinoceros\6.0\Localization\<your language>\Support

just find it out. thank you!

Ok…I find and it works. however I can not directly add some “my colors” on the enclosed tab modifing the txt color. I’d like to avoid to go every time in " other" colors .Do you have any advice for this!?Untitled-1

Don’t think you can via Properties - I think those are hard coded.

There are a few other solutions, the easiest is maybe to set up a custom toolbar that has some hard-coded custom colors, that way it’s one click.

Color picker?
