Color blocking... time trial? New terms for me.
Color blocking - just a graphic image centered around a few main "blocks" of complimentary or contrasting colors. In this case the dark green trees are one main "block" of color, the lighter green grass is another, and the yellow car is a focal point still in the same general color palette.
Time Trial - a "race" where the objects to complete a lap or laps in the fastest time, but you're alone on the course. Fastest Time of the Day (FTD) wins
I used to compete in these - now I have more fun shooting them. As I get older, the thought of blowing a tire at 165 MPH becomes a little more intimidating
