Question

Is there a method for changing the LSB value of java.awt.Color RGB components?

Answer 1

Turning a bit on:

int value = someValue | 0x1;

Turning a bit off:

int value = someValue & (~0x1);

Toggling the bit on or off if it was off or on before:

int value = someValue ^ 0x1;

In other words:
someValue is binary OR’ed with a number with the LSB on so the resulting number will have its LSB on too.

someValue is AND’ed with a number with all bits except LSB on so the resulting number will have LSB OFF.

someValue is XOR’ed with with a number with the LSB on, so the resulting number will have its LSB toggled.
