Anyone can explain how speed is applied to ships???

You can google the swgoh ship stats calculator. But basically, gear and mods (dots and level, but not color or stats) are what influence all ship stats including speed. Crew ability levels influence it as well.

Blue damage is special damage (non crit), red is physical damage (non crit), yellow is crit damage, and white is bonus and true damage.

Can you explain what you are wanting to know about thermal detonators? There are a number of teams that have interactions with them.
