matplotlibの色の一覧をpandasで作る
pythonのmatplotlibでグラフを書くとき時々色を指定したくなりますが、その度に色の名前や16進数のカラーコードを検索しています。しかし毎回検索するのは面倒なので色の一覧を出力するプログラムを書きました。
検索してよく出てくる色の一覧は画像ファイルですが、このプログラムではpandasを使って表形式でまとめているため、色の名前やカラーコードのコピペがしやすいです。
コードは次の通り。
import matplotlib as mpl import pandas as pd df = pd.DataFrame(list(mpl.colors.cnames.items()), columns=['name','hex']) df['hsv'] = df['hex'].map(lambda x:list(mpl.colors.rgb_to_hsv(mpl.colors.to_rgb(x)))) df['color'] = df['hex'] df = df.sort_values(by='hsv').reset_index(drop=True).drop(columns='hsv') display(df.style.applymap(lambda x:f'background-color : {x}; color : {x}', subset='color'))
これを実行すると次のような表が出力されます。
あとは適当な色の名前をコピーして使ってください。
個人的には 'dimgray'、'tomato'、'darkorange'、'gold、'darkcyan'、'skyblue' あたりが好みです。
