EffectFactory.EFFECT_TINT , issue with Color intensity

[ShankarKakumani]

I am trying to apply Tint using EffectFactory.EFFECT_TINT

below is the code I am using

        val hue = effectFactory.createEffect(EffectFactory.EFFECT_TINT)
        hue.setParameter("tint", Color.argb(255, 6, 206, 249)))
        
        

using the above code, tint is getting applied. but I tried giving alpha(0-255) values as 50, 100, 150, and 200. The intensity of the color is always the same.
