Need to match RGB values!

Hi, any help appreciated on RGB color matching.

Background: In my Carrara Octane plugin this is simple - put in the RGB value, and get the color you expect.

Not getting anything like this in the Blender Octane. The colors come out super bright.
In the image below, we see I can lower the grey scale slider at right, but then I do not have the needed number reference.

This should be simple. What am I missing?

I really need the colors in the boxes at right.

Thanks for the help,
Rick

Update.......I dropped the above image in the uv image editor and sampled the color swatches.

Please let me know if there is a better recipe. Seems to work fine though.

"Blender uses (0 to 1.0) values to express colors for RGB and HSV colors."
You can get the right colour in picker in two ways:
1. Convert your standard (0-255) RGB value to HEX value,
2. or divide RGB values by 255:
