how do i Change the color of single string in multiline edit box

Hii,

I have created a GUI using guide in MATLAB R2017b, where Action log panel is there,in that i am printing all gui's output results in multiple line, i can change color of all text in edit box , but i want to change color of single string without changing color of other older strings.

for example if operation is successful then "operation is successful " this string should be in green color, if operation is failure or some error is there then " operation is failed " this string should be in Red color

So, as per above image in edit box "Get status command successfully sent..." should be in green color
