Blue and purple
A normal Bunsen burner has a chimney which contains gas, a collar to adjust the air hole, a air hole that will leak gas, a gas tap that provides gas to the burner and the rubber tubing leads gas to the burner.
Very hot. 70-100 degrees celcius. HOT!
What colour the flame is has totally got to do with how much oxygen is allowed into the Bunsen, the flame can be anywhere between a bight orange to blue, all the way to being almost unnoticeable. This is what make them dangerous if unattended as you wont know there burning until you are. Low air easily visible flame, High air flow, and it becomes very difficult to see.
A "yellow" flame is the coolest, while a "blue" flame is the hottest. The "colour" of flame is chosen depending on the temperature required for the reaction that you want. There is no incorrect colour.
The flame is white and very luminous.
The tip of the blue cone is the hottest part of the Bunsen burner flame.
This is not a very well worded question. What do you mean by why should it be used? I Bunsen burner is used for heating things, usually in a lab setting.

in bunsen burner complete combustion takes place,it produces blue flame and blue region is the hottest part of a flame.so the whole flame is very hot,either the outermost part of flame.

A luminous flame is blue and is air/oxygen rich and occurs when the Bunsen vent is open. A non-luminous falme is very yellow and smoky and is fuel rich. It occurs when the Bunsen vent is closed.

The Bunsen Burner was named after Mr Robert Bunsen himself a German man that had a crazy idea. Mr Bunsen came across they idea and people soon had the bunsen burner in 1855.
how to be safe using a Bunsen Burner:1. never leave the flame unattended... especially when on the blue flame.2. always wear safety glasses.3. don't heat up anything metal because they will get very hot.4. don't let young children near the Bunsen burner when it's on.5. always have someone watch it.6. turn the gas off immediately when the flame goes out.
Twist the collar at the bottom of the Bunsen burner to allow more oxygen to mix with the methane. This will produce a blue flame that is very hot and may be difficult to see, so be careful.
