Feature requestGood first issue

描述

I'm using resemble via the wdio-image-comparison-service. It works great, but I would love to be able to specify that the erroneous pixels present in image 1 (my baseline) are green (expected) while the errors from image 2 (the comparison) are red. Hopefully that makes sense. Basically I want it to display like a git diff.

研究方向
Examine the Resemble.js source code, particularly the output rendering logic in 'resemble.js'. Look for where error pixels are colored, likely in the `compareImages` or `createImageData` functions. The feature request is to add an option for users to specify separate colors for baseline and comparison errors (like a git diff). Check if any existing PRs or forks address this. Since there are no linked issues or PRs, the implementation would involve modifying the output color mapping to accept two color strings instead of one, and applying them to the respective image differences.
