Front Drivers Spring question (Colour reference help needed)

[Stoneyginger]

i have recently bought my cooper s and now found that i am having issues with noise on left turns, i inspected the springs on my ramp today however due to the car being on warranty i am not touching or sorting anything i simply inspected it. What i found is as follows:

Rear Springs are Light Blue and Yellow
Front passenger side is Purple
front drivers side is however just black and i cannot see any stripes on it but the car sits at the exact same height.

is it possible that a spring has been broken at some point and replaced with a non like for like spring. On left turns at low speeds i can hear a rubbing noise which is quite loud so i think it may be down to a wrongly situated spring maybe?

OEM springs are black, so definitely aftermarket ones you have

ok i think i didnt make myself clear here, the colours are the little stripes that are painted onto the black springs however the front drivers side has no little paint marks, my understanding was that the stripes were an actual mini reference to what type of suspension it was

Ah, right. In that case I have no idea - I don't have OEM springs
