i found this very informative article with names of cultivars and care tips.

they give a 'color description' for each cultivar - but it's not so easy to visualize.
i took this pic on the streets of South Beach, FL - looks just like OP's.
could this be :
‘Pink Christmas’: cream, becoming suffused with pale pink & reddish streaks?
you can see a list of varieties that they sell - all thai names though

'Boon Sangsom' looks pretty close.
