Color Map Editor - Pick Screen Color NOT matching

I am trying to maintain the same color for my figures. I tried to use the pick screen color tool in the Color Map Editor. However, as you can see the blue color is not exactly matching. it is more purple rather than dark blue (Attached a fig below)
Could you please let me know what I should do to get the exact color? Thanks for the help!

Hello @Akash

The color difference is maybe due to the lightning of the Scene. You can disable the light kit with the Light Instpector panel (from the View menu), and check again the picked color.


Thank you for the response.
I unchecked the box of “Light Kit” within the Light Inspector panel. Then I reset the color map and chose the blue color but still, it’s the same.

@Akash , can you illustrate what discrepancy you can see ?

I have attached a pic above. You can see that the red color in the Color Map Editor matches the legend below. However, blue doesn’t. The blue color in the Color Map Editor is more purple rather than dark blue. That’s the discrepancy I notice.
Thanks for the help!

Where does the bottom of your image is coming from ?

The bottom image is the legend from a paper. My supervisor asked me to maintain the same color map used in that legend. I have just cropped that legend and attached it next to color map editor for comparison

Then what makes you think they should look the same ?

I used the pick screen color tool and click the blue in that legend. Then it should change to the same blue color, right? But it’s not. Its working for red but not for blue

I have no idea what you mean by “pick screen color”.

It is this tool:

There is no reason for the color map to be the same. To obtain the same result, you need the complete definition of the color map in the paper, eg: the RGB definition of each color used and associated value.

Okay, thanks. I gave the RGB values in the Select Color toolbox.
It works inside the toolbox as you can see the blue is correct. But in the contour it is purple.
Why is that happening?


This is the interpolation in use. You can change the colorspace if you want.

I don’t understand. Could you please explain? What is colorspace and where to change it?
Thank you!

It worked finally I changed to “RGB” rather than “diverging”
