You can do that using this method
/// <summary>

/// This method highlights the assigned text with the specified color.
/// </summary>
/// <param name="textToMark">The text to be marked.</param>
/// <param name="color">The new Backgroundcolor.</param>
/// <param name="richTextBox">The RichTextBox.</param>
/// <param name="startIndex">The zero-based starting caracter position.</param>
public static void ChangeTextcolor(string textToMark, Color color, RichTextBox richTextBox, int startIndex)
{
if (startIndex < 0 || startIndex > textToMark.Length-1) startIndex = 0;

System.Drawing.Font newFont = new Font("Verdana", 10f, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, 178, false);
try
{
foreach (string line in richTextBox.Lines)
{
if (line.Contains(textToMark))
{
richTextBox.Select(startIndex, line.Length);
richTextBox.SelectionBackColor = color;
}
startIndex += line.Length +1;
}
}
catch
{ }
}
