FET array - logical switch
That looks good.

A few things to consider.

This FET looks good but when using other types be careful about the extremes of gate threshold voltage, many common types such as 2N7000 have a worst case threshold of >3V and so are not suitable for use with 3.3V logic.

The voltage required for the LED varies with the color - red is lowest at ~1.7V green is next at ~2.1 but blue and white may need more than 3V and so can't be driven from a 3.3V power rail without some more complexity (a charge pump for instance).

These days you can get enough light out of an LED for most uses with only 1-2mA.

Since the current requirement is so low you can drive the LED straight from a logic signal  (with a resistor) and you don't really need a discrete driver.
