Component to display Colour

Hi,
I need a component that gets input such like “255,0,0” or “White” and can transform it to color display in the GH environment.

Thanks,
Clemens

‘Display | Color | HSL’ or RGB or fRGB or CMYK or HSV or… etc.

No I dont want to split the colors. I´d like to have a visualisation directly on the GH canvas. Like this:

They don’t split colors, they generate colors for use with Custom Preview.

How about posting your solution?

This may be overkill but I found a list of “web safe” colors here:

Then parsed the JSON format in Python. As noted on the page, there are duplicate color names in this list so I used only the first 16 colors and ignored the rest. There must be CSV or JSON formats with unique color names but I was too impatient to search further.

The Python could be ignored by internalizing the Color Name/Values data param.

The teal group uses a PVL component posted recently by @AndersDeleuran to initialize two Value List components:

  • ‘Colors’ in purple group has both names and color values.
  • ‘Color Names’ in white group has only names and does a lookup of the color value associated with the color name passed to the ‘M’ input of MIndex (Member Index).

Here is the Python code:

import json

json_colors = json.loads(JSON)

colors_A = []
for aColor in json_colors:
    rgb_A = []
    for rgb in aColor['rgb']:
        rgb_A.append(str(aColor['rgb'][rgb]))
    colors_A.append(aColor["name"]+'|'+','.join(rgb_A))

colors = colors_A

Created a CNLU (Color Name Lookup) cluster that returns RGB color value for color name.
