The coloring of the actively growing leaves is dependent on exposure. These are all pics from the same plant, from cutting pieces off and sticking them in various places & pots over the years.
With no direct sun:
In mostly shade with brief periods of direct sun. This exposure-look is much more purple in person, my camera fails miserably at purple:
This deep purple was in a spot with no direct sun, outside, in very bright shade with dapples of light through an oak tree.
With direct sun most of the day, it becomes more reddish than purple, leaves smaller, pointed upright (though not apparent from this example of dangling foliage,) and the node distance is much shorter.
Such a range of conditions is not possible inside but you should be able to find a spot where it has the hue you love. Your particular plant looks like it may be getting the reddish look of more-sun end of the spectrum. If so, that's the easiest adjustment, and so rarely does one get to even think about suggesting backing off of the amount of light for an indoor plant. Easy because there's always less light inside.
