While Jupyter notebook, the notebook plugin from VSCode, and many other terminals support rendering 24-bit color sequences, Google Colab seems not render the 24-bit colors correctly for now that such highlighted texts are displayed in black and white.

For example:

print('\x1b[38;5;28;01mimport\x1b[39;00m \x1b[38;5;21;01mos\x1b[39;00m\n')

Describe the solution you'd like
Given a 24-bit color sequence, render it to correpsonding RGB colors in HTML display correctly (not pure black).
