For this "breath of fresh - garlic", I have chosen a neutralized complimentary color scheme of "oranges" and "blues". Considering color harmony, I will keep my palette simple, choosing only a few colors within my color scheme that represent a variety in value (lights, darks, and midtones), softness, temperature (warm and cool colors) and chroma (intensity).
Form and value in painting are built by layering pastel of various hues and color temperature. Most often, I will work spatially, working an area as it occurs in space on the 2D plane. I begin with the most distant space and work towards the most forward space. That said, I continuously go back and make minor adjustments to previously worked areas to balance the colors and values throughout the painting. In general within these spaces, I work from dark to light and harder to softer pastel.
Studying the light as it falls on the subject, I first lay in the darker and "cooler" color followed by the warmer darks. I consider this the foundation darks, followed by the lighter, softer color "on top". By accurately portraying these values, form and depth are created (and thus the "special effects" of painting).
