I constantly forget the names of the colors I want to use and keep coming back to this question =)
The previous answers are great, but I find it a bit difficult to get an overview of the available colors from the posted image. I prefer the colors to be grouped with similar colors, so I slightly tweaked the matplotlib answer that was mentioned in a comment above to get a color list sorted in columns. The order is not identical to how I would sort by eye, but I think it gives a good overview.
I updated the image and code to reflect that 'rebeccapurple' has been added and the three sage colors have been moved under the 'xkcd:' prefix since I posted this answer originally.
I really didn't change much from the matplotlib example, but here is the code for completeness.
import matplotlib.pyplot as plt
from matplotlib import colors as mcolors
colors = dict(mcolors.BASE_COLORS, **mcolors.CSS4_COLORS)
# Sort colors by hue, saturation, value and name.
by_hsv = sorted((tuple(mcolors.rgb_to_hsv(mcolors.to_rgba(color)[:3])), name)
for name, color in colors.items())
sorted_names = [name for hsv, name in by_hsv]
n = len(sorted_names)
ncols = 4
nrows = n // ncols
fig, ax = plt.subplots(figsize=(12, 10))
# Get height and width
X, Y = fig.get_dpi() * fig.get_size_inches()
h = Y / (nrows + 1)
w = X / ncols
for i, name in enumerate(sorted_names):
row = i % nrows
col = i // nrows
y = Y - (row * h) - h
xi_line = w * (col + 0.05)
xf_line = w * (col + 0.25)
xi_text = w * (col + 0.3)
ax.text(xi_text, y, name, fontsize=(h * 0.8),
horizontalalignment='left',
verticalalignment='center')
ax.hlines(y + h * 0.1, xi_line, xf_line,
color=colors[name], linewidth=(h * 0.8))
ax.set_xlim(0, X)
ax.set_ylim(0, Y)
ax.set_axis_off()
fig.subplots_adjust(left=0, right=1,
top=1, bottom=0,
hspace=0, wspace=0)
plt.show()
Additional named colors
Updated 2017-10-25. I merged my previous updates into this section.
xkcd
If you would like to use additional named colors when plotting with matplotlib, you can use the xkcd crowdsourced color names, via the 'xkcd:' prefix:
plt.plot([1,2], lw=4, c='xkcd:baby poop green')
Now you have access to a plethora of named colors!
Tableau
The default Tableau colors are available in matplotlib via the 'tab:' prefix:
plt.plot([1,2], lw=4, c='tab:green')
There are ten distinct colors:
HTML
You can also plot colors by their HTML hex code:
plt.plot([1,2], lw=4, c='#8f9805')
This is more similar to specifying and RGB tuple rather than a named color (apart from the fact that the hex code is passed as a string), and I will not include an image of the 16 million colors you can choose from...
For more details, please refer to the matplotlib colors documentation and the source file specifying the available colors, _color_data.py.
Answer from joelostblom on Stack Overflow
python - Named colors in matplotlib - Stack Overflow
help color code keywords for python
I created a python script to generate color palettes from images (info + github link in comments)
What does the blue and yellow represent in the python logo?
Colors are a Monty Python reference (toward the bottom):
Bridgekeeper: What...is your favorite color?
Galahad: (relieved) Blue! (starts across; oops) NO!

Matplotlib uses a dictionary from its colors.py module.
To print the names use:
# python2:
import matplotlib
for name, hex in matplotlib.colors.cnames.iteritems():
print(name, hex)
# python3:
import matplotlib
for name, hex in matplotlib.colors.cnames.items():
print(name, hex)
This is the complete dictionary:

You could plot them like this:
import matplotlib.pyplot as plt
import matplotlib.patches as patches
import matplotlib.colors as colors
import math
fig = plt.figure()
ax = fig.add_subplot(111)
ratio = 1.0 / 3.0
count = math.ceil(math.sqrt(len(colors.cnames)))
x_count = count * ratio
y_count = count / ratio
x = 0
y = 0
w = 1 / x_count
h = 1 / y_count
for c in colors.cnames:
pos = (x / x_count, y / y_count)
ax.add_patch(patches.Rectangle(pos, w, h, color=c))
ax.annotate(c, xy=pos)
if y >= y_count-1:
x += 1
y = 0
else:
y += 1
plt.show()
Hello I am new to python and coding in general as in very new and I basically know nothing and I am looking to learn, I was wondering if anyone can help me change the color code of ym my python text because as of right now its all the same color and I feel it would help me to learn better if things like print were color coded aswell as variables, errors etc. Basically just a good coding color system, as thats what I used on my school computer but can't quite figure it out on my own PC. Thankyou
