Adding color to characters, digits in an HTML file

Question

Adding color to characters, digits in an HTML file

Is it possible to individually style each letter, number, and symbol in an HTML document with a unique color? I am interested in creating a text editor that applies specific colors to each glyph for those who have grapheme-color synesthesia. While there are existing programs available, I want to challenge myself by developing one using JavaScript and improve my skills. I also plan on expanding this concept to a reader application in the future.

One method is to enclose each character within an HTML element, such as a span, and assign a class corresponding to the character's value to apply the desired style. I intend to implement this approach in a React Native application as well.

Are there any more efficient or appropriate methods to achieve this level of customization?

Using regular expressions to add spans in a basic way. By replacing the string with a function, you can introduce dynamic elements for determining color.

var paragraphs = document.querySelectorAll("p");
[].forEach.call(paragraphs, function (element) {
  element.innerHTML = element.innerHTML.replace(/(\S)/g, "<span>$1</span>");
});

span { 
  display: inline-block;
  border: 1px solid black;
  width: 20px; text-align: center;
}

<p>Mary had a slice of bacon. It cost $0.75 and tasted great.</p>
<p>Bill had no bacon. He was sad!</p>

Asides from looping through and replacing, there doesn't seem to be another method available.
