System.Windows.Forms.RichTextBoxhas got a property of type Colorof the name SelectionColorwhich gets or sets the text color of the current selection or insertion point. You can use this property to mark specific fields in your RichTextBoxwith the colors you specify.
System.Windows.Forms.RichTextBox有一个Colorname类型的属性，SelectionColor它获取或设置当前选择或插入点的文本颜色。您可以使用此属性RichTextBox用您指定的颜色标记您的特定字段。
Example
例子
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 Browserif you would like to highlight the text within the Linesin RichTextBoxgiving it's value
注意：您可能避免计算通过使用RichTextBox.Find(string str)可通过添加Object Browser，如果你想突出内的文本Lines中RichTextBox赋予它的价值
Example
例子
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

I found this extension method that gives you the ability to change the color of the string as well as inserting a newline value:
我发现这个扩展方法使您能够更改字符串的颜色以及插入换行符值：
public static void AppendText(this RichTextBox box, string text, Color color, bool AddNewLine = false)
{
if (AddNewLine)
{
text += Environment.NewLine;
}
box.SelectionStart = box.TextLength;
box.SelectionLength = 0;
box.SelectionColor = color;
box.AppendText(text);
box.SelectionColor = box.ForeColor;
}

you can use Run object to change the color at runtime
您可以使用 Run 对象在运行时更改颜色
private Run GetForegroundColor(string strInformation, Brush color)
{
Run noramlRun = new Run(strInformation);
noramlRun.Foreground = color;
return noramlRun;
}
for more complex scenario like change the color based on requirement then visit blow link
