IF colors are a big concern, click on this Trinket link and run a cool program:  https://trinket.io/pygame/f5af3f7500

Python has a great many named colors you can choose by using the color’s name. A condensed list of officially recognized symbolic color names can be found in the program below.  The page “… more Colors” shows another view, compliments of PySimpleGUI. Here is a quick link: https://wp.me/P8cRX9-Mv

Here is the program I modified to display the chart on a 23″ monitor. If you want it smaller, reduce the font size to 10 and delete the width=17 option. I did not write the program that generated the chart – wish I knew who should get the credit. I modified it to produce a much larger jpg, to use only the “grey” spelling to differentiate the shades of grey (duplicated by “gray” in their name) and assign fg to black or white depending on luminance.
