easy ombre flower

i have to say that i didn’t come up with this design, a friend of mine showed me a pic of flower made this way but then i couldn’t find where the picture came from to give proper credit, i tried making it myself for what i could figure out and i loved the result and was so easy to make that i decided to share it! so here it is!
hope you like it!
