Final answer:
To produce green with an unequal mixture, blue should be combined with yellow. The resulting color can range from bluish-green to pale green depending on the proportion of blue and whether the mixture is with a colorless substance.
Step-by-step explanation:
To create the color green using paint or pigment, you need to mix blue with yellow. When these two colors are combined in unequal proportions, with a higher quantity of blue, the result is a bluish-green shade. However, when mixed in equal amounts, the result is a true green. In cases where an unequal mixture of blue with yellow produces a lighter shade, the resulting color might appear pale green, especially if it's mixed with a colorless or white substance that dilutes the intensity of the color.
