You'd need to modify the if (red == 255 && green == 255 && blue ==
255) { to your values, however, the issue is that the fader goes in
steps of 10 so it may never reach your values.Therefore you need to
use

if (red >= 243 && green >= 244 && blue >= 255)

The Math is actually really easy, the only thing that might not be
explained well is Math.ceil() which returns the next integer.
Math.ceil(3.6) is for example 4

The other bit dirty bit about the function is that it just returns
when the final colour is reached.
