System.Windows.Forms.RichTextBox has got a property of type Color of the name SelectionColor which gets or sets the text color of the current selection or insertion point. You can use this property to mark specific fields in your RichTextBox with the colors you specify.

Example

RichTextBox _RichTextBox = new RichTextBox(); //Initialize a new RichTextBox of name _RichTextBox
_RichTextBox.Select(0, 8); //Select text within 0 and 8
_RichTextBox.SelectionColor = Color.Red; //Set the selected text color to Red
_RichTextBox.Select(8, 16); //Select text within 8 and 16
_RichTextBox.SelectionColor = Color.Green; //Set the selected text color to Green
_RichTextBox.Select(0,0); //Select text within 0 and 0

Notice that: You may avoid calculations by using RichTextBox.Find(string str) which can be added through Object Browser if you would like to highlight the text within the Lines in RichTextBox giving it's value

^Example

RichTextBox _RichTextBox = new RichTextBox(); //Initialize a new RichTextBox of name _RichTextBox
_RichTextBox.Find("Account 12345, deposit 100$, balance 200$"); //Find the text provided
_RichTextBox.SelectionColor = Color.Green; //Set the selected text color to Green
