Fixes #0000 (<=== Replace 0000 with the Issue Number)

@Olusamimaths please write issue number here.

[harshkhandeparkar]

Please multiply the alpha by 255 and not 256.

[LeoDog896]

@Olusamimaths please add the issue number, and also change the multiplier value to 255 instead of 256. Other than that, a great fix!
