* "Par de zapatos" means "pair of shoes"
* "Del color una" is grammatically incorrect. It should be "del color de una" meaning "the color of one" or "de un color" meaning "of a color".
Here are some ways to correct and make sense of the phrase, depending on what you want to say:
* "Un par de zapatos del color de una flor" - A pair of shoes the color of a flower.
* "Un par de zapatos de un color" - A pair of shoes of one color.
* "Un par de zapatos del color de un atardecer" - A pair of shoes the color of a sunset.
To get the meaning you're looking for, please provide more context. For example, are you describing the color of the shoes? Or are you saying the shoes are the same color as something else?
