Modify the color of the text for the initial letter appearing in the sentence

I am currently exploring the possibility of altering the font color of the initial instance of a letter in a div. For example, if the String were 'The text' and I desired to make the color of 'e' yellow, then only the first e would be impacted. 'The text'. This is what I have managed to accomplish so far:

<div class="translation-esan-div">
  {{$scope.someValue}}
</div>

Upon accessing this element using:

angular.element(document.getElementsByClassName("translation-esan-div"))

the text() value that gets returned is {{$scope.someValue}} rather than the angular evaluated text.

The content within $scope.someValue could vary. A predefined css class specifying the color would already be in place. The specific letter that needs to change would be included in the associated controller. How can I simply modify the color of a particular letter?

One potential approach is to utilize JavaScript for extracting the data from a specific element, manipulating it as needed through standard string operations, and then reintegrating it back into the original container with two nested <span> tags. The inner <span> could replace certain characters while applying a predefined style using the class attribute "custom-styled-span".

Here is a potential solution using the ngBindHtml directive:

angular.module('app',['ngSanitize']).controller('MyController', ['$scope', function($scope) {    
    $scope.process = function(letter, text){
        if(letter && text){
            var index = text.indexOf(letter);
            var result = '';
            if(index != -1){
              for(var i = 0 ; i < index; i++)
                result += text[i];
              result += '<span class="yellow">' + text.substr(index, letter.length) + '</span>';
              for(var i = index + letter.length ; i < text.length; i++)
                result += text[i];
              return result;
            }         
        }
        return text;
    }
}]);

.yellow {
    color: yellow;
 }

<script src="//code.angularjs.org/snapshot/angular.min.js"></script>
<script src="//code.angularjs.org/snapshot/angular-sanitize.js"></script>

<div ng-app='app' ng-controller="MyController">
   letter:
   <input ng-init='letter="e"' ng-model='letter' type='text'/>
   <br>
   text:
   <input ng-init='someValue="The text"' ng-model='someValue' type='text'/>
   <p ng-bind-html="process(letter, someValue)"></p>
</div>

            }         
        }
        return text;
    }
}]);

.yellow {
    color: yellow;
 }

<script src="//code.angularjs.org/snapshot/angular.min.js"></script>

<div ng-app='app' ng-controller="MyController">

   text:
   <input ng-init='someValue="The text"' ng-model='someValue' type='text'/>
   <p ng-bind-html="process(letter, someValue)"></p>
