I have a short question, about coding. I have 2 hsv colors.

I have a short question, about coding. I have 2 hsv colors. In my example I have a HSV color e.g. green on a strip with the fill_solid function. Then I wants to fade in a function to another HSV color from the first color in a loop (step by step, with a little delay in it) and I don’t know which HSV is the last value on the stripe --> I have to read from the array. How can I do this best? I have found: leds[i] += newTint; But this is ony for RGB, but is this the right function for my wish?
Thanks

Problem solved,with rgb compare…
