ValueError: Invalid RGBA argument when trying to set colors on pie chart
I am trying to create a pie chart using three dictionaries and coloring the labels with the color codes specified, these are my dictionnaries:

And this is my attempt to create the piechart:
from collections import Counter
language_counts = Counter(language_families.values())
colors = [dict_langfam2color[fam] for fam in language_counts.keys()]
plt.pie(language_counts.values(), labels=language_counts.keys(), autopct='%1.1f%%', colors=colors)
plt.show()
The problem is that I keep getting this error: ValueError: Invalid RGBA argument: '(153, 153, 0)', anyone has an idea?
Solution
Not only you need to get rid of the quotes but you need also to convert the color values in dict_langfam2color to the expected format by matplotlib, i.e floats in the range of 0-1 (as mentionned by @JohanC) :
| Format | Example |
|---|---|
| RGB or RGBA (red, green, blue, alpha) tuple of float values in a closed interval [0, 1]. | (0.1, 0.2, 0.5)(0.1, 0.2, 0.5, 0.3) |
Source : [Specifying colors]
#add this bloc to your code--------------------------------------------
from ast import literal_eval
dict_langfam2color = {k: tuple(map(lambda x: x / 255, literal_eval(v)))
for k, v in dict_langfam2color.items()}
#----------------------------------------------------------------------
language_counts = Counter(language_families.values())
colors = [dict_langfam2color[fam] for fam in language_counts.keys()]
plt.pie(language_counts.values(), labels=language_counts.keys(), autopct='%1.1f%%', colors=colors)
plt.show();
