Rotala Indica (the real one) is NOT a low light plant. That said, very few actually own it, and what you buy commercially is not actually Indica - it is rotundiflora that you find commercially available (and mislabelled obviously). I only make a point of this because there is real Indica in the hands of folks in this area - and as it isn't common at all, I'd hate to see it killed with folks not knowing how different it is.
Anubias Gold requires more light than normal Anubias. Similar to other marbled and off color mutations, the color is a function of dead pigment cells, which makes the cells that remain work harder to photosynthesize.
Myriophyllums, Hydrocotyles (not left floating that is), Bacopas, and rotalas may live (or may not, low light to non planted folks is REALLY low light), but will be ratty and long legged - especially in deep tanks like a 150g. Downoi as well looks absoutely horrid when it struggles along in low light.
