Is your outdoor tub in direct sunlight? It might help a little. As their name suggests make sure the roots are red. In my experience the leaves are mostly green and turn red as the plants get a bit older and extend out. When kept indoors or in an aquarium I have never had any red leaves nor do the red roots show well.

I have a hex bowl of pearl weed and redroot floaters. It gets direct sunlight and the plants have extended out of the water.

I've never been able to get mine to be red either. I'd have to turn my light up to max (currently at 50%) and would rather not deal with algae. My plants are doing fine they just aren't red.

Hi when my red root floaters were flowering I had them in pretty much completely still water directly under a finnex stingray which might help

There is a red leaf root floater  . Phyllanthus Fluitans .They are high priced around $10 but they multiply.

Hmmm, I wonder if the red comes from dosing Iron? Have you tried that?

Red root floater color, (Phyllanthus fluitans as @Golden Ramsmentioned) depends primarily on light levels but is also going to be somewhat related to nutrients.  If they aren’t getting nutrient levels needed, they aren’t going to do well.  They fortunately don’t appear very picky about nutrients.  Light appears to be the primary factor.  I have red roots that have grown much more red in different tanks, but I don’t currently have them in a tank with the light close to the plants or under a strong light.  If I moved some over to a tank with the light very close to the water surface, I’m sure they would get more red.  They are more picky about not having much surface agitation and also don’t like much splashing or dripping water on their surface.

I have Fluval Plant 3.0 lights on all my tanks, could be why they are such a beautiful bright red. Don't really know as I am not a plant guy.

Light is the main factor. 
 

Most have plenty of iron. I would test to make sure you need iron before dosing. Some forms of algae loves iron.
