Coincidence?

When I was a child my favorite color combination was blue and yellow. I did not know until more recently that the shades of these colors that I liked most are the colors of the Ukrainian flag. Is this a coincidence or something more meaningful. I do feel a connection with that country. I do hope there is peace there soon. Too many people have lost their llives there to war and famine in the last century. My heart goes out to Ukraine.
