[Peak and Pine]

I am having trouble differentiating between these greys for a business formal setting

...which is similar to my failure to differentiate between the leaves on my porch in October since they all look the same. Not a bad choice, yours, because to the untrained eye there is no choice. I however have a trained eye, taught it to roll over, play dead, etc. and I cannot tell the difference. Park your worry and turn off the engine.
