Which color corresponds to the hex code #FFFFFF?

The hex code #FFFFFF corresponds to the color white. In the hex color system, colors are defined using a combination of six characters, which represent the levels of red, green, and blue (RGB) in a color. Each pair of characters corresponds to one of these primary colors.

In the case of #FFFFFF, the first two characters "FF" represent the red component, the next two "FF" represent the green component, and the last two "FF" represent the blue component. The value "FF" in hexadecimal notation is equivalent to 255 in decimal, which is the maximum intensity for each color channel. When all three channels are at their maximum intensity, the result is white.

This makes white the only option that can accurately be associated with the hex code #FFFFFF, while the other colors listed (red, blue, and black) do not have this representation in the hex color model.
