In one of my stories, there is a planet covered with lakes and rivers called Hogeates. The soil, sediment, and flora of the planet give it a great yellow color when viewed from space. Besides an abundance of sulfur, what other chemical compositions would cause the rock and soil to have a yellow hue?
sulfur would give a yellow hue, but when it reacts with other elements, the compounds created could be of any color. Elemental sulfur is usually found near volcanic activity, and it usually isn’t long before it reacts with something and creates a compound which will look very different.
If you want a planet with lots of sedimentary features like earth that have a yellowish hue, you would want weathered felsic rocks (igneous rocks similar to granite) that have a bit of iron oxide in them. Sandstones (which largely form from eroded granite) with a yellowish color are mostly quartz but the yellowish hue is due to limonite which is a common iron oxide that often comes in various shades of yellow, red, or orange. , other varieties of limonite can also come in black
