ESL question with/by/or something else

Question

I need to modify a picture with pink color.

Or

I need to modify a picture by pink color.

Or

I need to modify a picture using pink color.

Which one is right?

Answer 1

It depends what you mean.

I need to modify a picture with pink color.

or more naturally,

I need to modify a picture with pink.

I need to modify a picture with the color pink.

This sentence could be interpreted as saying you need to modify a picture by adding the color pink, either to change an existing color to pink or to mix it with pink (e.g. a black-and-white version of the Komen Foundation logo). It could also be interpreted as saying you need to modify in some unspecified way a picture which already contains the color pink (e.g. a picture of a carnation).

I need to modify a picture using pink color.

i.e.

I need to modify a picture using pink.

I need to modify a picture using the color pink.

This sentence explicitly says you will apply the color pink to the picture, but I don't think sounds as natural as using "with."

The last example,

I need to modify a picture by pink color.

is not typically used in English.

Answer 2

I would use modify a picture with pink or modify a picture using pink but not modify a picture by pink.
