Achieving the perfect shade of grey using food coloring requires a delicate balance of primary colors. By combining blue, red, and yellow food coloring in varying proportions, one can create a range of grey hues, from light to dark.
Understanding the color wheel is key to creating the desired shade of grey. Blue and yellow, when mixed, create green; red and yellow create orange; and red and blue create purple. By adjusting the ratios of these primary colors, one can achieve a neutral grey tone.
