What plant colours other than black could be available on a red dwarf planet?

Hello! I'm no scientist so I've reached the limit of my knowledge. I was wondering if any of you smart beans out there would be able to help me figure this out? Here are the specs of my system;

Kereiol is a 2 billion year old quiescent carbon-rich M star with a temperature of 3,100 kelvins. If it flares at all they are tiny. It has four orbiting planets, only one of which, Liskuel, is within the goldilocks zone. Liskuel is 0.15 AU from Kereiol and has an orbital period of 35 days.

Liskuel is a tidally locked wet, rocky carbon-born planet with an active core. It is 1.5 times the size of earth, but with a similar mass and gravity as unlike our planet which is dominated by oxygen and silicates, it is rich in aluminium, titanium, silicon, carbon, and lithium and mostly comprised of quartz or diamond. 70% of the surface is covered in water, with especially deep oceans on the nightside.

I'm thinking the range of plants; plants closest to the nightside reflect the peak radiation to use other less intensive light and appear black while plants closer to the substellar point use chlorophyll f and infrared light and appear a reflective bright blue-green metallic. Could there be other colours? Would these colours be possible?

Cheers!
