blue – lan-ser
Written as lánsè or lanse
To remember that blue is pronounced lan-ser (lanse) in Mandarin Chinese, use the following mnemonic:
Being dressed in blue the lancer (lanse) thought he would be more difficult to see against the blue sky behind him.

Note: To clearly distinguish that we are dealing with the word "blue" we have enhanced the picture by connecting the word "blue" with "blue skies".
