Hard to believe under all this snow that there could ever be grass this green again...but we can hope. I had challenged myself to use a super limited palette here, using only cadmium orange, ultramarine blue, and white and I did almost paint the whole thing using only those two. Those two colours will produce a really nice value range, but the tone of the colours produced is muted (that's what happens mixing complimentary colours) much like an overcast day. I wanted that spring feeling...sunshine... so squeezed out a blob of cadmium yellow pale onto the palette. Interesting how that one colour can add such zing. I really love fooling around with colour, it has such an ability to change how we see things.
