Why do East Slavs use (light) blue colour?

[Benyzero]

Not the best coloring for the outside of the building, but I find that color chill and aesthetic anyway

[Jana]

I like it, looks fresh and sweet. Light blue is my second favorite color.

[Nurzat]

same shit in countryside northeast Romania, light blue, light green, more recently even pink and orange.. it looks awful

[Perunovsin]

So that the houses look like lapis lazuli

[Incal]

Our Slovak community in Serbia also like blue colour.

Is it a recent community or they have historical roots?

Our Slovaks settled in 18th and 19th century when northern part of Serbia was part of Austrian empire.

First Slovak settlers from area around Tatra migrated to Bačka during the time of Karlo I; in 1720 Slovaks settled in Bajša, in 1740 in Petrovac and Futog, and in 1742 (during the time of Maria Theresa) in Bezdan. Some of them also later moved to Srem. In 1760, 120 Slovak families were settled in Selenča, but they later moved to Stara Pazova in Srem.

In 1783, Slovaks settled in Kisač, Veprovac, Gložan, and Topola. Part of them also settled in Bajša. In 1790-1791, Slovaks settled in Pivnice, in 1792 in Stara Palanka, and in 1793 in Novi Slankamen. In 1784-1787, Slovaks settled in Slovanski Bardan. In 1792 Slovaks settled in Bačka Palanka. Some of them moved in 1788 to Aradac and Ečka, and some of them later also moved to Lalić.

In 1800, Slovaks settled in Kovačica, and in 1806 and 1809 in Padina. In 1806, one group of Slovaks settled in Čoka, and in 1809 in Šupljaja. In 1825, Slovaks settled in Dušanovac, and in 1830 in Stari Lec. In 1850, 20 Slovak families were settled in Grk. In 1868, Slovaks settled in Marienfeld, from where they later moved to Vojlovica. In the same time, some Slovaks also settled in Ivanovo. In 1887, Slovaks were settled in Elizenhajm, and in 1899 in Silađi colony near Apatin.

Maybe it has practical purposes? For example, light blue resembles water so it might scare away various insects and bugs (also woodworms), who avoid getting drowned. This is just my guess.

[Arūnas]

but I prefer our post-German red (bricky) - funny thing - the Soviets seem to be less red than here

[Kerlovic]

I think its pretty

[Salty Ears]

Chto by bylo veselo! To add better atmosphere into the endless white and grey months. Blue, green, orange house could be а good landmark during a blizzard.
