If Statement conditioning

ok, this is a bit of a crazy ask, but I have been banging my head all day and there must be an easier way of doing this!

I have 2 values and I want to test these values against each other but there could be a + or - 10 difference between them that is acceptable.

All I keep thinking is that I will have to write a huge statement with lots of OR's in there i.e

if (red = red1) || (red == red1 + 1) || (red == red1 + 2) etc.....

Please someone put me out of my misery and tell me there is an easier way!!!

Simple: Assuming these are integer values:

if (abs(red - red1) <= 10) {
}

If instead you have float values:

if (fabs(red - red1) <= 10.0) {
}

There are several other absolute value functions available depending on the type of values. See this SO answer for more info

Check if the absolute value of the difference between the two numbers is less than 10.

if (abs(red - red1) <= 10)
    ...
