Flicker is indication HID is failing, trying to run on high voltage from the igniter rather than high voltage from the ballast.
I can tell any difference in these pictures from L to R. I don't see the yellow. Are these Xenons? or LED's? What year car?
Time for a new set of Xenon bulbs.
Color change is not a noted issue with aging LED.

‘Xenon’s’ are arc lamp burners rather than incandescent bulbs. The components of HID are the xenon filled short-arc burner, the high voltage ballast and the higher voltage igniter.

You have HID (Xenon) bulbs. As these age, they will change color, usually turning a pinkish/yellowish color. just replace the bulbs (both sides).
LED not HID

it’s hard to show on the pic, if you look on the ground you will notice it better.

Not sure if they are LED or HID

"I thought I had LED not HID"
How many switches on the end of your turn signal stalk? (One equals HID, two equals LED.)
This is what I have.
Is it LED?

That is your light switch. Look at the end of your your TURN SIGNAL stalk.

Also, I can tell you have HID's from the photo you posted. LEDs have both lenses on each side and they are all illuminated with high or low beams. HIDs only use the outer lenses - the inner lenses are "dummies" to maintain the proper "BMW Look".
