Same mother but different colour?

[BettaFillet]

After my mamas gave birth about a month ago, shrimplets are doing well now, some are already 1cm. however, one weird observation was that 95% of my shrimplets from the sakura mamas are orange but slightly red tinge and 5%(2 shrimplets) are colourless witha slight blue tinge. is that actually possible? or the colour just hasnt developed?
