The colors of the fabric dyes may not affect
the drying time much, especially when the dyes
come from the same company.
Factors that can affect drying time much more
include the amount of dye used, the area of the
fabric, the temperature of the dye bath, the
ambient temperature (for dyes that need to sit
after they have been applied to the fabric), the
degree of air circulation, the type of fabric, and
how the fabric was processed in the factory.
If all these factors are equal for two pieces of
fabric, and only the color of the dyes differs -
blue vs. red, for instance (not light pink vs.
dark pink because that may change the amount of
dye) - then you may not see a substantial
difference between the drying times of the two
dyes. You can test this idea by using two
different colors of tie-dye.
You should do the experiment yourself and find
I predict that dark fabric in the sun will dry
faster because the dark color will absorb more
light and so evaporate the water faster.
I predict that dark fabric in the shade
will dry slower because the dark color will
radiate away more heat and so the fabric will be
cooler and evaporate more slowly.
I predict that the humidity and
temperature of the air on the day that you do
the experiment will have a larger effect on drying
time than the color of the fabric would.
I recommend you to think about what you could do
to determine the effect and ask questions on parts
of the cientific method that you should
review. You might consider what the "drying"
process entails, the factors which affect the
steps of that process, and how color might
influence those factors.
I don't think color would affect drying time
unless the fabric was dried in the sun, where the
different colors would absorb different
wavelengths of sunlight.
Here's an answer from a google search of your
How Does Color Affect Drying Time? |

In this experiment, it is expected that red,
yellow, and orange colored garments will dry
faster because these garments absorb high
energy, high frequency wavelengths of light
that will raise the temperature of the garment and
increase the rate of drying.
