Indicator side repeaters

[DHGTR]

Does anyone know for certain if the side repeaters have to be amber, if they do ....................... just how amber???? mine are a bit on the red side of amber. Just as i'm here, i must have had a late night when i did the rear lights . one side has 2 brake lights and the other only one, i know we have to only use the single for SVA, but it doesnt half look good with both!
