The lighting theme is hot.
Orange, red, and yellow may be cooler in terms of degrees Kelvin but they are associated with warm things like the sun and fire. The big bright hues of the sky reflect the excessive warmth of the lighting. The sky is on fire, red hot. The golden ball of gaseous matter shines like the largest gem and greatest treasure in the sky and makes the sky its hue. It is yellow and white with a hint of orange like a match flame glowing bright to light a candle. It is thus a mass producer of heat parching the landscape like how a used match is charred. It silhouettes and gives a highlight of red to the things beneath it like what a dreamer might imagine the Martian landscape to look like. This red makes the world seem hot like a laser beam has been pointed at everything. The distribution is wide engulfing the entire sky and majority of the landscape in the warm colors and causing the silhouetting to occur. The light source glows with warmth, and the lighting is as hot as a bright red pepper tastes as a consequence.
