Beginner question

Hi. I’m completely brand new to Arduino and coding. I’ve put together a small beginning project to flash an RBG LED in rainbow colors, in rainbow order. Pretty simple. Thing is, it seems to flash red, green, green, slightly different green instead of red, orange, yellow, green. I’m not sure what might be going on. I do get red, green, and blue, so the hardware seems to be working. Color values were taken off one of the many internet sites…Any help much appreciated!

Thank you.

I’d guess the code we don’t know anything about is a tad off.
