Question from a home brewing DM

[BalorClub54]

In one of the Dragon quest magazines, it drops a possible plot line of Tiamet having a sister. It was only ever a one off, so they didn't flesh her out very much. I'm going to make her the main antagonist in my campaign, and I want ideas to flesh her out. Including a name. All that's really set is she is the godess of Orange, Purple and Yellow dragons.

Welcome to ENWorld

Orange dragons are NE, favor tropical lakes/steamy rainforests, and sometimes are called "Sodium Dragons." They often ally with evil rainforest-dwelling monsters and fight for territory with black dragons. They dwell on land, but hunt in the water. Their breath is a stream of acidic mercury (similar to a black dragon).

Yellow dragons are LE, favor salt flats/marshes/lakes, and sometimes are called "Salt Dragons." They often run afoul of bullywugs and yuan-ti which consider yellow dragon wyrmlings/eggs a delicacy. At Young age they adapt to water and can breath underwater, hunting herds on land and fish in the sea equally. Their breath is a cone of salt crystals (the one time I ran a yellow dragon in AD&D I had its breath act like the petrifying breath of a gorgon).

Purple dragons are NE, favor caverns that open onto grasslands/hills, and seemed to have become more associated with the Underdark as D&D as advanced through the editions. They oust copper dragons from their territory, generally are quarrelsome with other inhabitants like hill giants or ankheg, and are brazen enough to challenge gold dragons to aerial duels. Their ability to predict weather allows them to hunt at night using thunderstorms to hide their presence as they raid herds and livestock and the occasional shepherd.

For a name, I'd go back to Babylonian mythology where "Tiamat" comes from. For example, Thalattē (or later Thalasia) was another name for Tiamat, as was Ummu-Hubur.

You could round up the number to 5 just like Tiamat, by adding the 2e/3e Brown Dragon and the 4e Grey Dragon.
