Dragonfruit handyed yarn

I love dragon fruit color. bright fuchsia and I thought it was good if I dyed my hand spun yarn with dragon fruit skin.

I put amount two dragon fruits skin with 1,5 litter water and heat it until boiled. The color is good, it turn to light fuchsia. then i let the water boiled for 10 minutes more, but the water color turn to be tea brown color. It's not the color I want, so I turn off the heat, i put my hand spun yarn into pan.

I sit the yarn and water overnight. In the morning I watched that the water became fuchsia color again, but the yarn's color became light  yellow

very light and the color is nice although this is not the color I want from the dragon fruit.
