I have very basic question but I can't find an answer

 

Template

I have this template that is based on 3 indicators

1- first one is used only 1 (slope direction)
2- second one is MACD Alert is used 3 times as shown (from 2 to 4)
3- third one is pipsfxgainer is used 3 times as shown (last 3 ones) 

 All I need to do is to read the graphs of each, I need at each indicator graph to read its color

1- for first one to read if it is blue or red
2- second one (3 ones) I need to read if it is red or green
3- same as 2

How can I do that on MQL4?
