Overview:
This Node works like a Constant.
Except you can choose your color value by entering a
- Hexadecimal color
- standard Nuke float color
- RGB 8bit color
More Information:
- Changing any value will update all other values respectively
- Colorspace conversions are taken into consideration. sRGB should do the job in the most cases though
- If bugs are found, please comment ;)
How to Install:
- the download contains a .nk file and can be pasted in live scripts
- for permanent installation, copy the HexColor.nk file to 'C:\Users\username\.nuke'
- edit the file 'C:\Users\username\.nuke\menu.py' and add the following line:
nuke.menu('Nodes').addCommand('Other/HexColor', lambda: nuke.createNode('HexColor.nk'))
Please login in order to download these files.

EDIT: Temp fix is to write expression in each RGB Float value to be the below divided by 255
When i input any HEX value, the RGB changes to the correct value, but the float does not.
The script editor says the following:
ValueError: unable to sample node for given channel (rgba.red) at current context
NukeX 11.0v1
version 10.5 v5
push $cut_paste_input
Expression {
expr0 input.color_8bit_r/255
expr1 input.color_8bit_g/255
expr2 input.color_8bit_b/255
name Converter
selected true
xpos -2460
ypos -897
}
The idea was to have a live conversion between all of the input fields.
I implemented a sample function to make use of the sRGB colorspace, so a web color is translated correctly.For now I only have issues, when Linear is set as colorspace.
Maybe a solution would be better with a switch at the end that is set to whatever conversion was done last and to avoid the nuke.sample() function, which is the cause of many errors.
edit: more difficult that I thought, because I still need to translate the values into the other knobs, after being procssed by the colorspace. Only way I can think of now is to find a python or TCL implementation of colorspaces (or just sRGB)
edit2: found this: www.cyril-richon.com/blog/2019/1/23/python-srgb-to-linear-linear-to-srgb and probably gonna implement this down the road.
