'Appearance' in the Bible

The appearance of Him who sat there was like jasper or sard; and encircling the throne was a rainbow, in appearance like an emerald.

The appearance of the locusts was like that of horses equipped for war. On their heads they had wreaths which looked like gold.

And this was the appearance of the horses which I saw in my vision--and of their riders. The body-armour of the riders was red, blue and yellow; and the horses' heads were shaped like the heads of lions, while from their mouths there came fire and smoke and sulphur.
