/jenkins/job/sonar/api/json?tree=jobs[color]

Executing above url will return colour which corresponds to the build status of the job.
All colours correspond to the url of the image except "nobuilt" OR "notbuilt"

Current:

URL of the image: /jenkins/images/48x48/nobuilt.png

color status: notbuilt

Expected
I expected color status to be nobility, same as url

Impact

This is breaking my API and I need to put some dirty code to fix for this image
