Tolumnia Tequila Sunrise in bloom

Pretty! I believe that temps while buds are developing can affect bloom color. I've seen the same thing happen on a couple of my Tolus

The very first flower is fading now. More buds are on the way though!

I'm posting one week old pictures. Now I know the sun light exposure is what cause the flowers develop orange cast on the skirt.
I moved the plant away from the window and the newly opened flowers are solid yellow again.
As of now, there are five new flowers with one more short spike growing that has three little buds.
