IBEW LMS circuit simulator

Good day everyone. I am currently working on my courses on LMS through the VEEP program for the pre apprenticeship.

In my current lesson there is a basic circuit simulator. It has us wire some basic circuits based on the assignment guidelines.

My problem is that it keeps telling me I am using the wrong color of wires for my ungrounded conductors. I have used black, and blue for my connections. Both have been wrong according to the grading notes. I am including some pictures and I hope that someone here can help me understand what it is I am doing wrong.

The source bundle has always been black, white, and green.

Thank you all.
