[Javascript] Gradually change hex color

[Chaosy]

I was wondering if there's an relatively simple way to increase hex color.

Currently I am using the following

particles[i].material.color.setHex(Math.random() * 0x808008 + 0x808080);

Which gives each particle a new random color. So I was thinking that it would be better to just increase it gradually so currentHexColor += 1;
Which would probably work for a while until it reaches the cap and goes completely white and is still there?

if (currentHexColor > 0xFFFFFFFF) { currentHexColor = 0; }

What is your question?

if (currentHexColor > 0xFFFFFFFF) { currentHexColor = 0; }

or just tick the hex color and do a modulus operation on it.

currentHexColor = (hexTick + currentHexColor) % 0xFFFFFFFF;
