For e.g. I have this sort of subtitle
1 00:01:55,201 --> 00:01:58,401 <font face="sans-serif" size="47"><font size="20"><b>It's absurd going to school every day. The school's closed today.</b><font color="#ffffff"></font></font>
Now I'm unable to figure out the font color. Is there a way to get the color chart or give names or something that makes it clear what the color of the sentence is ?
