QUESTION
I have the columns of a dataframe plotted as separate histogram subplots. For each subplot, I want the bars coloured according to the value in a separate list. I have managed this by making a cmap of it and manually cycling those colours, however, is there a way to add a colorbar to the side to show what values these colours belong to? This is what I have right now:
...ANSWER
Answered 2021-Apr-23 at 20:56Instead of doing all the normalization steps manually, it probably is easier to create a norm. In this case a norm that maps the values from 4000 till max to the range 0,1 needed for the colormap. Note that converting to hex isn't necessary.
With the norm and the colormap a ScalarMapple can be created with all the necessary information for a colorbar:

ANSWER
Answered 2021-Jan-28 at 08:44The common way to declare a hex color is using 6 digits. When using the 3 digits format, you are shortening the 6 digits format. This only works if the digits in the positions R (so 1,2), G (3,4) and B(5,6) are equals.
Eg: You can write #00CCFF in 3 digits format as #0CF, but you cannot do the same on #425416
Maybe this thread can make my point more clear.
QUESTION
I'm trying to split an image depending on the colors it contains.
My previous steps have been to simplify it to just 3 colors using the KMeans algorithm that Sklearn offers and I get a result like the following image.
Now I need to split it in 3 images one for each color. And obtain something similar to this (I have done it with photoshop).
The examples are done in black and white because really if I can do the division, I no longer need the colors. But I would do just as well with 3 color images.
Mask 1:
Mask 2:
Mask 3:
I found this question, but I can't achieve my goal.
I have thought about separating by channels, but I think it is wrong.

Answered 2020-Dec-10 at 18:22We could get the closest image as @fmw42 suggested. (Thank you very much sir, I appreciate your suggestion.)

compute the rmse difference between your test color and the color values of all of the color names. Take the one with the smallest rmse. You will need to convert from hex to r,g,b to do the rmse computation.
For each image name, hexadecimal value, convert each hexidecimal value to the rgb.
QUESTION
I have large lists containing RGB values for pictures. I use numpy to create patterns and/or pillow to load pictures and convert them to 3D-numpy arrays (int32). Now i want to restructure my array into hex-strings in a weird way: Three hex-strings for R, G, B in this structure: '0000FFFF', where the first 4 characters always have to be zero, then 2 characters represent pixel n+1 and the last 2 cahracters represent pixel n. I already have done this with a code which takes too long for larger images and i require some improvement. What i got so far:

When creating a PyQt5 tab widget the background colour is whiter than the background of a normal widget. I am looking for a way to get the tab exact background colour.
Some good examples that relate to this question are:

How to make the background color the same as the form background?
The most common suggestions to get the background colour is to use:
...ANSWER
Answered 2020-Jun-30 at 19:19The colors of a palette are only a reference for how the style will actually paint widgets. Some widgets use gradients to show their contents (consider buttons, which usually "glow" the color given for the palette Button role). Some styles even paint some widgets using roles that seem unrelated to that type of widget.
QTabWidget behaves in a similar way (depending on the style), so even if you get its background, it will probably painted with a slightly different color.
A possible solution is to set the background of the widget using stylesheet, while still keeping the palette reference:
