Delicious Rainbow Bagel

I made a pretty bagel with color.
I like to eat it with plenty of cream cheese.
Make a pretty and delicious bagel~
It was cooked at a low temperature so that the grilled color did not appear much.
When baked at 150 degrees, the bread comes out flat,
When I baked it at 190 degrees, it wasn't pretty because there was too much color to be baked.
So I baked it at 160 degrees.
