All things being equal, color of food coloring will not make a difference. If the ingredients used to make the coloring are different, then there may be a slight difference. This would be a great science experiment.
actually you might need to look elsewhere
How fast do detergent dissolves in water
no
The color may effect how fast-slow it will melt because the may have different ingredients then the others. Also, darker colors attract more light and light = heat. So if the slushies are not in the dark, the color will affect their rate of melting.
how fast a substance dissolves
Yes, but the dye causing the coulour will probably not evaporate, leaving a (liquid or solid depending on the dye) residue. This will evaporate as well when it is heated sufficiently, although a lot of dyes would probably combust before this temperature is reached.
Instant coffee dissolves very quickly in hot water.
Carnations typically absorb water at a rate of 1-2 inches per day. When food coloring is added to the water, the carnation will absorb the colored water through its stem, resulting in dyed petals in the color of the food coloring. The absorption rate may vary depending on factors such as the freshness of the flower and the concentration of the dye.

Sugar dissolves faster in warmer water compared to salt. This is because increasing the water temperature provides more energy to break apart the sugar molecules, allowing them to dissolve more quickly. Salt, on the other hand, already dissolves relatively fast in water regardless of temperature, but it tends to dissolve slightly faster in warmer water as well.
The rate of dissolving would be temperature dependent.
cheap, fast
