It is a luminous yellow flame. 🔥
The "air-hole" of a bunsen burner allows some of the flame to escape so that the heating flame does not become too hot. A flame that is too hot can damage laboratory equipment. When the air hole is closed it is a yellow sooty flame like the fires we have at home.
Yes,it can .But it might take longer time to heat
The air hole in a Bunsen Burner allows air to mix with the gas prior to burning so that the flame can be adjusted as desired.

The two colours are yellow - when the air-hole is open, and blue - when the air-hole is closed.
it's to prevent a strike-back
When the hole of a Bunsen burner is half closed (or half open) the flame is mostly blue-violet in color throughout, with no orange/yellow apparent as it would be with the hole fully closed. When the hole is fully open, the flame divides into a pale voilet color outer part with a cone of intense blue color within.

The function that covers the air hole in a Bunsen burner is the collar.
