There would be nothing but heatless yellow flame for a while.
Still, the fire made an appealing sound and had a true yellow flame.
The fire was the wrong color, bright yellow flames where they should be blue.
The right side makes only a yellow flame, not hot, no hissing noise.
"We saw a big ball of yellow flames roll down the street."
It went up in a rush and a shout of yellow flame.
The light that we see on Earth does not come from the yellow "flames" of the sun.
Blue and yellow flames licked his red hand, but they did not burn.
The night was perfectly black and still, no moon or stars, the only light coming from the thin yellow flame near their feet.
They were bright, brighter than the yellow flames on the other wood.
