Problem Statement
For 2 Colors in RGB:
(R1, G1, B1)
and (R2, G2, B2)
,
Brightness index is:
( 299*R1 + 587*G1 + 114*B1) / 1000
Brightness difference is:
Absolute difference in brighness indices
Hue difference is:
|R1 - R2| + |G1 - G2| + |B1 - B2|
where |x|
is the absolute value of x
If Brightness difference is more than 125 and the Hue difference is more than 500 then the colors have sufficient contrast
Find out if the given color combos have sufficient contrast and get all the tests passing.
