Final answer:
The tick mark on primary data sources corresponds to the primary colors (red, yellow, blue), and the tick mark on secondary data sources corresponds to the secondary colors (orange, green, violet) created by mixing primary colors.
Step-by-step explanation:
The question pertains to the use of primary and secondary colors in blending, which is a concept in the study of arts. When using a blend, the color of the tick mark on the primary data sources would correspond to the primary colors, which are red, yellow, and blue. These colors, when mixed, create the secondary colors: orange (red and yellow), green (blue and yellow), and violet (blue and red). Consequently, the tick mark on the secondary data sources would correspond to these secondary colors. Additionally, tertiary colors are formed by mixing a primary color with a secondary color, leading to hues like red-orange or yellow-green. When mixing colors, especially pigments, the result is a subtractive process, leading to darker colors or black when all primary colors are mixed. The combination of colors also plays a role in determining complementary colors and analogous colors, which appear across from or next to one another on the color wheel, respectively.
