The "Saw That, Mixed This" Challenge

Day one of a new challenge

And not completely sure where this one is going . . .but the idea being, a practice that gets me outside before the summer comes to a close and painting what I see in my backyard, either from life or a photo. My "rules" this time are, drawing or painting from life if at all possible, without creating more stress in an already too full schedule. If weather or time makes that impossible, then from a photo, but the photo has to be from something I notice while outside that day. My challenge  will be to look for the predominant color of the subject matter, and then mix that color, rather than using a straight from the tube color. So, lets see how this goes. 
I started by choosing a familiar subject, the frog name Robert, (because he came from a plant, jumped out of the hanging basket I was watering) who lives at the front door. We think he has taken on the roll of the doorbell since he lives where one would be if we had one and his croak is so loud that an approaching visitor would be well announced regardless of our doorbell deficit.
I limited my palette to sap green, yellow ochre and Phthalo Turquoise, mixed all my greens with those three colors I added  burnt sienna, quinacridone purple and indigo to darken shadows. I cooled down my greens and shadows with purple and warmed them up with burnt sienna.
​This is going to be fun.
