I doubt it is warm enough to cause color differences up in Canada yet? unless your room is super warm.
When I had thick waxy red fragrant phals in the past, it was the buds that developed during the heat of summer months that opened up with red spots against yellow background. Those tiny red spots give me funny feelings. I don't know what it is (not a matter of taste for me) but looking at them really just disturbs me. I don't know if it's because the pattern reminds me of certain insects of reptiles, but they just have that effect on me.
But in the winter months, they always bloomed out fully saturated intense dark red.
In the following summer, I could not look at the flowers and gave them all away.
