Are we going to see any updates to the earthlike planets or waterworlds?
Its not like chlorophyll is the only way space plants could photosynthesize.
If our atmosphere were just a little different, or our Sun burning a slightly different chemical mixture and generating light of a noticeably different color, our plants would be likely to have evolved to different shades than is the current average. In fact, it has been proposed that exactly this scenario happened in days gone by when our Sun was less bright and our atmosphere had a different composition. According to the Purple Earth Hypothesis, early life on earth used Retinal (aka Vitamin A) instead of chlorophyll, and the simple algae were purple instead of green.
Another purple option is bacteriochlorophyll (similar chemically to chlorophyll, but absorbing somewhat different wavelengths of light). Combined with carotenoids, this is what makes 'purple bacteria' purple. Many purple bacteria use hydrogen sulfide rather than water (producing sulfur rather than oxygen) in their photosynthesis process.
Recently, Fungi has been discovered that uses melanin (a black pigment that humans, and many other species, use to protect against ultraviolet solar radiation) to conduct a photosynthesis-like reaction at Chernobyl to turn radioactive gamma ray emissions into food.
Class M Stars emit most of their light in the infrared spectrum so plants evolving under such a star might develop a black pigment that absorbs as much light as possible or even a pale pigment that does the majority of its absorption in the infrared range alone.
Plants on a planet orbiting an Class F Star would find it most efficient to produce a predominantly orange photosynthesizer.
The blue wavelengths of light are more energetic and would make more efficient photosynthesis, so it unlikely that blue photosynthetic pigments would evolve or dominate (since a blue pigment would reflect the blue light instead of absorbing it). However, it's not inconceivable that a planet orbiting very close to a blue star, or being bombarded by radiation from a somewhat more distant Class O Star might develop blue pigmentation to deflect the strongest and harshest parts of the light. So while blue is the least-expected color for an alien forest, it can't be completely ruled out.
