" pruh" , that's a P, and an R, and a schwa.

" pruh" 由 P 音、R 音和弱读音组成。

By the way, the Flap T appears between two vowels in unstressed syllables, but also between an R and a vowel in unstressed syllables.

顺便说一下，Flap T 出现在非重读音节的两个元音之间，也出现在非重读的 R 和一个元音之间。

Only it begins with an R and a C and it's bright red color.

只有它以 R 和 C 开头，并且是鲜红色。

I also like to start using just the " r" and a vowel first, because I think that's easiest, so saying: " ra" or " ro" , or " re" .

我也喜欢先开始只使用“r” 和一个元音， 因为我认为这是最简单的，所以说：“ra” 或“ro” 或“re” 。
