Based on our current understanding of biology and photosynthesis, blue vegetation is highly unlikely to occur on G-type stars' planets. Plants on Earth primarily appear green due to the presence of chlorophyll, a pigment that absorbs light in the blue and red parts of the spectrum and reflects green light. This makes green light the most efficient for photosynthesis. However, the color of vegetation on other planets might differ depending on the star's spectrum. G-type stars emit light with a maximum output in the yellow-green range, which is similar to our Sun. Vegetation on planets orbiting G-type stars is more likely to evolve to maximize the absorption of light in the yellow-green wavelengths, similar to plants on our planet. While it is theoretically possible that some alien lifeforms might have evolved differently and have blue pigments, it is uncertain whether these would be able to undergo photosynthesis efficiently under the light of G-type stars. Photosynthesis requires access to specific wavelengths of light, and blue pigments would likely absorb light in the blue and green parts of the spectrum, limiting the energy available for photosynthesis. Thus, the occurrence of blue vegetation on G-type stars' planets is considered highly improbable based on our current knowledge.

Determining the specific percentages for vegetation color on planets is difficult since it depends on various factors such as the planet's atmospheric composition, the star's spectrum, and the evolutionary history of the alien life forms. On Earth, the dominant pigments responsible for vegetation color are chlorophyll a and chlorophyll b, which give plants their green color. However, for the sake of imagination, let's propose some percentages for each pigment you mentioned, keeping in mind that these are highly speculative and not based on scientific evidence: 1. #107a1b (Chlorophyll) - 70% 2. #609416 (Chlorophyll b) - 10% 3. #b8b112 (Xanthophyll) - 5% 4. #c26213 (Carotene) - 3% 5. #cc1414 (Phycoerythrin) - 1% 6. #400023 (Anthocyanin) - 2% 7. #0a0a0a (Melanin) - 2% 8. #800080 (Bacteriorhodopsin) - 1% 9. #0b33d4 (Phycocyanin) - 1% 10. #705f2a (Unknown pigment) - 5% Again, these percentages are entirely speculative and fictional since we currently do not have any evidence of the presence of these specific pigments or their distributions on any exoplanet. Future discoveries and further scientific understanding can potentially shed more light on the possibilities of such variations in alien vegetation color.
