Color of GatsbyContentfulFluid_tracedSVG fill

Since this repo is more active and up to date, cross-posting from here: contentful-labs/starter-gatsby-blog#98

Loving using Contentful with gatsby-image, but would be nice to be able to use a query to change the fill color from the default light gray. Gatsby-plugin-sharp has this built into their query with traceSVG: { background: "#fbfafc", color: "#dbd4e2" } - any chance of something like this that would be easily reproducable with Contentful?
