The compounds of Cobalt as CoCl2 and Cu2O are red.
The compounds of radium has a red color in fire.
These compounds are iron oxides.
Hemoglobin is the iron oxygen carrying protein which gives blood its red color
The cause of the color is not known. It may be due to the presence of phosphorus or sulfur compounds.
Chromium is a metal and, like most metals, it's a sort of shiny gray color ("silvery"). Chromium compounds can be most any color: red, orange, yellow, green, blue, and violet chromium compounds are all known. The color depends on the oxidation state of the chromium and also on what ligands are present (particularly in chromium (III) compounds).

Strontium compounds provide red color (and is often found in road flares as well). Calcium compounds produce orange. Charcoal (carbon) or a mixture of iron and carbon provide the gold/yellow color. Sodium compounds produce a yellow color. Barium compounds produce green. Copper compounds produce blue. A mixture of strontium (red) compounds and copper (blue) compounds produces purple. Silver/white can be produced by: aluminum, magnesium, titanium, or antimony (III) sulfide.
lithium and calcium compounds as well as strontium
The cause of the color is not known. It may be due to the presence of phosphorus or sulfur compounds.
The different colors come from different chemical compounds, so yes, there is a difference other than color.
Red. Strontium is often used in fireworks to give off a deep red colour when burned.
Neon does not form any compounds.
Chromium is a metal and, like most metals, it's a sort of shiny gray color ("silvery"). Chromium compounds can be most any color: red, orange, yellow, green, blue, and violet chromium compounds are all known. The color depends on the oxidation state of the chromium and also on what ligands are present (particularly in chromium (III) compounds).
Compounds of bivalent manganese are pink.
The Compounds that give fruits and vegetables their red color are very sensitive to acidity. As long as they are acidic they stay red, but when they become non-acidic they turn blue. When you saute red cabbage, the acids evaporate off and it can turn blue. All you have to do is add lemon juice or vinegar to bring back the bright red color.
