You can use the setOnShowListener method of the AlertDialog to get the buttons and apply a different color and their own listeners, here you have an example in Kotlin:

val alert : AlertDialog?
val alertView = LayoutInflater.from(context).inflate(R.layout.alert_add_product, null, false)

val builder = AlertDialog.Builder(context)
    builder.setCancelable(false)
    builder.setView(alertView)

    /**Create positive and negative buttons**/
    builder.setPositiveButton(android.R.string.ok, null)
    builder.setNegativeButton(android.R.string.cancel, null)

    alert = builder.create()

    /**Listener called when the AlertDialog is shown**/
    alert.setOnShowListener {

         /**Get the positive button from the AlertDialog**/
         val positiveButton = alert.getButton(DialogInterface.BUTTON_POSITIVE)

         /**Set your color to the positive button**/
         positiveButton.setTextColor(ContextCompat.getColor(context, R.color.bluePrimaryDark))

         /**Set listener to the positive button**/
         positiveButton.setOnClickListener({
              alert.dismiss()
         })

         /**Get the negative button from the AlertDialog**/
         val negativeButton = alert.getButton(DialogInterface.BUTTON_NEGATIVE)

         /**Set your color to the negative button**/
         negativeButton.setTextColor(ContextCompat.getColor(context, R.color.bluePrimaryDark))

         /**Set listener to the negative button**/
         negativeButton.setOnClickListener {
              alert?.dismiss()
         }
    }

    alert.show()
