Read ws2811 and use arduino pwm pins to dim individual leds

I have 2 very bright rgb leds and would like to use at the end of a rgb string
I know for the electronics I need to use mosfets to control each red green and blue led in the rgb led I have all of this set up and can generate the colors I need using an arduino so my only problem is reading the ws2811 I have found numerous tutorials for using an arduino to output ws2811 to control a strip of lights but what I am trying to do is dim leds according to data received from the end of a ws2811 string that is receiving data from another arduino
