Question

I saw an example online:

private int[] colors = new int[] { 0x30F8F8F8, 0x30EAEAEA };

I am not sure what the first chars represent, but the last 6 look like hex numbers. Is this correct?

Answer 1

Depending on the format, it looks like those colors are in RGBA (or some other re-ording of them.)

Essentially,

0x30 = Alpha component
0xF8 = Red component
0xF8 = Green component
0xF8 = Blue component

If you know which one is alpha, you can replace it with 00, or if it at the beginning, remove it

0xF8F8F8
0x00F8F8F8
