There were many MF colors that I loved, but watermelon wasn't one of them. I used Lure Craft. That might change the outcome, but yeah.......as mentioned, salt it the culprit here as it will change the look of ANY color. I think you'll have to play around with it until you find what works best for YOU.
Hats off, though, for using salt as a new pourer. I probably poured for 2 years before adding salt. lol
