Text color in header / body of the card

Continuing from How about encapsulating each cards (in DOM level)? - Thoughts & Feedback - Supernotes Community

The ban on <style> tags requires a significant amount of typing effort when writing cards. For example, if I want to beautifully highlight Sunday in red as an h3 heading while creating a weekly plan, previously I could simply assign a separate class style. However, after the ban, I have to input a lengthy string like <span style="color: var(--colors-red)">Sunday</span> , which is somewhat inconvenient. As observed in programming code and syntax highlighting examples, text color greatly assists in understanding the content of a card. I would appreciate it if at least a convenient syntax related to text color could be added.
