difference between きれい and キレイ


I was reading the lyrics of a song called 春先小紅 by 矢野顕子

There is this line that says:

> きょうはなんだかキレイです

I was wondering why キレイ above is written in Katakana and not in Hiragana?
Isn't katakana used for foreign words?




Words that are usually written in hiragana, when written in katakana, just
mean it's being emphasized. You might see this in written works too, in which
case the English equivalent is a word being made bold. I hope this helps!
