Felicia, I've only seen such discoloration on emerging leaves. The symptom remained on the leaves when they matured but it got lighter in color and changed its pattern somehow. Strong sunlight and heat can also get the color darker. This same FMV can cause both leaf malformation/discoloration and color break on flowers.

As for the CB (due to virus) on flowers, it is already there once the flowers emerge as well. I have never seen CB (due to virus) developed on one day old (or older) flowers (except for the case of the CB may be more intense in color because of stronger sunlight and heat). The CB that developed later on mature leaves are normally due to other causes such as insect or chemicals and its patterns are different as compared to those caused by virus.

Felicia, It is interesting to see the new leaf that is starting to emerge. However, new leaf from FMV infected plumeria may discolor or be healthy green as seen in the attached pic.
