Trying to reproduce plot with a certain colormap

kgb2020 · August 11, 2017, 6:25pm

Hello everybody,

I have this figure done by a colleague quite a while ago in matplotlib:

https://image.ibb.co/cxGKSF/tst0.png

Unfortunately, I no longer have contact with my colleague to ask the particular colormap she used in matplotlib. I have looked through the gallery at https://matplotlib.org/examples/color/colormaps_reference.html but I am unable to find that colormap she used there.

Can anybody recognize the colormap she used in that plot?

Thank you!
Best, Kris

Hi Kris,

That one is called ?jet?, though it looks like she applied a bit of
a normalization to it to move the (green) center to lower values?

https://matplotlib.org/users/colormapnorms.html (see the last
subsection: ?Two linear ranges?)

Cheers, Jody

Not jet, it doesn't go through cyan. Looks more like coolwarm, to me, or
maybe RdYlGn_r (but the yellow isn't right, either...).

I am also not completely convinced it was made in matplotlib. The 3d plot's
projection isn't the same as mplot3d's projection.

Hi all,

I agree with Ben that it does not look like jet to me: the bright light
blue seems to be missing. FWIW, "Spectral" (with a capital S) might be
the closest colormap among the built-in ones in Matplotlib, but it is
still more ?pastel-ish? than Kris? example.

Best,
Adrien

This image has pretty clearly been converted to CMYK hence the dullness. Pretty convinced that's what jet looks like after a CMYK conversion.

CMYK conversion was done in Illustrator.

You could still argue that matplotlib?s ?jet? gets darker at the
high reds and low blues, and maybe the cyan is more bright. But you
have to be pretty careful w/ CMYK conversions because it depends on the
profiles used etc etc. I?d buy the argument that this is a matlab jet
versus a matplotlib jet, but I think most of the perceived difference is
because a CMYK conversion happened somewhere along the way.

Cheers, Jody

PS, I note the image *says* that it is RGB, but then my converted image
also says the same thing.

Thank you Jody, I did not know that CMYK conversion could alter colors
that much; that is interesting.

Ben, maybe my cheap screen is tricking me here, but I would have say
that what is still missing in the CMYK conversion is the cyan/bright
blue part, not the yellow one. Anyway, as Jody wrote, it might just be a
matter of CMYK profile, doesn?t it?

Best,
Adrien

Yes, there is also still the cyan. I am doubtful that just having a
different profile would be enough to change this. I think either RdYlGn_r
or coolwarm is a lot closer than jet put through a cmyk conversion. I am
going with the philosophy of the simplest model that explains the most
amount of the data observed. A cmyk conversion isn't out of the question
because many publications do that conversion. But if that was the case,
then putting RdYlGn_r or coolwarm through CMYK conversion might actually
bring it closer to your example than CMYK converted jet is.

Also, keep in mind, I am still not convinced that this is even matplotlib
in origin due to certain features of the 3d plot (I am the maintainer of
mplot3d). I don't know if it looks like matlab's version, though, as I
don't have experience with it.

Thank you Jody, I did not know that CMYK conversion could alter colors
that much; that is interesting.

Ben, maybe my cheap screen is tricking me here, but I would have say that
what is still missing in the CMYK conversion is the cyan/bright blue part,
not the yellow one. Anyway, as Jody wrote, it might just be a matter of
CMYK profile, doesn?t it?

Best,
Adrien

    You could still argue that matplotlib?s ?jet? gets darker at the
    high reds and low blues, and maybe the cyan is more bright. But you
    have to be pretty careful w/ CMYK conversions because it depends on
    the profiles used etc etc. I?d buy the argument that this is a
    matlab jet versus a matplotlib jet, but I think most of the
    perceived difference is because a CMYK conversion happened somewhere
    along the way.

    PS, I note the image /says/ that it is RGB, but then my converted
    image also says the same thing.

Hi,

Thanks for the replies. I use MATLAB so I am familiar with jet; but the colors in my colleague's plot looked too "pastelized" that I had my doubts, and finally decided to ask.

Best, Kris
