It is only very slightly more dense than pure water.
Yes it does you see that the water changes because the food colouring atoms are less dense than the water atoms which causes to "merge" together.
The density of blue food coloring can vary depending on the brand and composition, but typically it has a density close to that of water, which is around 1 gram per milliliter.
Dense
When something is not as dense as water, it is said to be less dense or have a lower density than water.
You can determine if a substance is more or less dense than water by comparing their densities. Water has a density of 1 g/cm3 at 4 degrees Celsius. If a substance has a density greater than 1 g/cm3, it is more dense than water. If it has a density less than 1 g/cm3, it is less dense than water.

The food coloring in cold water on top of warm water mimics the process of mantle convection, where cooler, denser materials sink while warmer, less dense materials rise. This creates a circulation pattern as the coloring spreads through the water, similar to how convection currents move in the mantle.
Unless the food coloring has some active ingredient, it will not affect the salt water chemically. In the environment, adding excessive food coloring to water may reduce the amount of light available to plants living in the water. Otherwise the coloring itself is innocuous.
Dense water sinks in comparison to less dense water.
Ice is less dense than water
no
Each and every object on this earth and the universe, has density, which is basically the measure of specific gravity experienced by the object. The denser the fluid, the greater the specific gravity and within a container, it will sink to the bottom and the less dense one will remain above it. You can try this experiment. Take water and oil and food coloring. Put a few drops of the food coloring in the water to give it a distinct color. In a glass, put equal volumes of water and oil, and let it rest. observe. The answer to this question is in this experiment. *P.S. : If you think that oil (in this case sunflower) is denser than water, do the experiment and prepare to be amazed.
A wooden block can be less dense than water.
no beacause a rubber duck floats and if an object floats in water, is is less dense than the water if it sinks it is more dense
To add food coloring to crystals, you can dissolve the food coloring in the water before starting the crystallization process. Simply mix a few drops of food coloring into the warm water solution containing the substance you’re crystallizing, such as sugar or salt. As the crystals form, they will absorb the colored solution, resulting in colored crystals. Alternatively, you can sprinkle food coloring directly onto the surface of the crystals once they have formed, although this may result in less uniform coloration.
I just did an experiment on this actually. Water molecules travel faster in hot water than in cold water. When food dye is added into hot water where the molecules are traveling faster, it mixes faster. In cold water, the particles are not traveling as fast and the food dye does not spread as fast.
If more dense, it will sink when put into water; if less dense it floats.
