nice and cool
凉 centers on a pleasantly cool temperature, the kind of refreshing coolness that feels nice and comfortable.
凉 is a variant form of 涼. It combines 冫 (ice) with 京, which likely contributes the sound. The ice radical reinforces the cool meaning.
The ice radical 冫 on the left cools down the tall capital city 京 on the right, making the whole scene nice and cool.
For リョウ, imagine a cool breeze blowing through a ryokan (旅館, りょかん) in Kyoto (京): the first syllable of ryokan, リョ, leads into リョウ, and the cool air makes the stay pleasant.
