Can chalk expressions be applied in color?
Because the surface can differ per location in terms of color and structure, we prefer to apply temporary chalk expressions in the color white so that visibility is always optimal. If desired, chalk expressions can also be applied in a number of primary colours, namely: black, yellow, orange, red, pink, purple, light and dark blue, light and dark green. Because the colors cannot be applied on top of each other because they then mix with each other, you can in principle only work with 1 color per placement.
