Python rgb colors work on Git bash, but not in node js. I figured out that CMD and PowerShell shows node js rgb colors.

Details

• Which terminal/shell are you running Git from?

Git Bash

• What commands did you run to trigger this issue?

$ node index.js
$ py index.py

index.js

const rainbow = () => {
    for(let i = 0; i < 15; i++) {
        process.stdout.write('\033[48;2;255;' + (i * 16) + ';0m.\x1b[0m')
    }
    for(let i = 0; i < 15; i++) {
        process.stdout.write('\033[48;2;' + (255 - (i * 16)) + ';255;0m.\x1b[0m')
    }
    for(let i = 0; i < 15; i++) {
        process.stdout.write('\033[48;2;0;255;' + (i * 16) + 'm.\x1b[0m')
    }
    for(let i = 0; i < 15; i++) {
        process.stdout.write('\033[48;2;0;' + (255 - (i * 16)) + ';255m.\x1b[0m')
    }
}
rainbow()

index.py

import sys
def rainbow():
    for i in range(15):
        sys.stdout.write('\x1b[48;2;255;' + str(i * 16) + ';0m.\x1b[0m')
    for i in range(15):
        sys.stdout.write('\x1b[48;2;' + str(255 - (i * 16)) + ';255;0m.\x1b[0m')
    for i in range(15):
        sys.stdout.write('\x1b[48;2;0;255;' + str(i * 16) + 'm.\x1b[0m')
    for i in range(15):
        sys.stdout.write('\x1b[48;2;0;' + str(255 - (i * 16)) + ';255m.\x1b[0m')
    sys.stdout.write('\n')
rainbow()

• What did you expect to occur after running these commands?

Same results when running both commands.

• What actually happened instead?

Node js command shows 5 colors, meanwhile, Python command shows rainbow.

node index.js

Can you try to run it through node.exe, i.e. node.exe index.js?

Apparently not...
