Is my spark good? Does color of spark matter?

I bought one of these OTC 6589's (OTC 6589) to test my spark to make sure I'm good with plugs/wires/coils/etc.

All 3 of the wires produces an orange looking spark. Can I check off my spark as being good or should I be seeing a blue spark? I've read a few things that says spark color matters and it should be blue. Does it matter in this case?

Also, it's a 1990 70HP Johnson.

Orange is usually a weak spark. You'll need to get a DVA rigged up to check CDI ignition systems.

What kind of problem are you trying to troubleshoot?
