Lightning

Yellow: The standard type with a touch of orange.
Pale: A hotter variation that may come from mixing with fire. Pale lightning can come in any available hue.
Purple: Not very rare, less hot but very shocking.
Blue: Hotter than purple, with a similar rarity. Blue electricity is also the least magnetic.
Green: Uncommon and related to earth, effective against inorganic targets.
Red: The rarest and coldest form but incredibly shocking, considered the purest type, akin to fire's purple variant.
Black: Extremely dangerous and unpredictable, as well as and partially due to being difficult to see. Black Lightning is theorized to result from very specific circumstances, such as the union of two elementals. Black Electricity is also extremely Magnetic.

Note: Magnetism allows dragons to push and pull metal, dragons can walk up metal walls with it as well.

Elements

White Ice: This is the standard variant, resembling cloudy glass when solid.
Cyan Ice: A natural derivative of white ice, it's slightly sturdier but not as cold.
Teal Ice: Thought to come from elemental impurity, teal ice is less cold than white ice but sharper, making it easier to cut.
Blue Ice: Blue ice is slippery, weak, and tends to fall apart easily. It has a slushy texture and is extremely cold.
Black Ice: This variant is extraordinarily sharp, even as it melts, and has an eerie glow emanating from its center.
Pink Ice: Revered as one of the purest ice variants, pink ice is the coldest among them all, but it's fragile when solid.
Purple Ice: Similar to pink ice, purple ice is also considered one of the purest variants and boasts extreme coldness, though it's prone to fragility when solidified.

White: White wind is the most common variant and the weakest.
Black: Back wind is the strongest and naturally coldest wind variant. Another dark dragon lineage trait, black wind is otherwise almost impossible to obtain unless one parent has dark dragon heritage. Black wind tends to displace air and oxygen, causing hollow objects to implode.
Tinted/Saturated: Tinted wind isn't as strong or cold as black wind, but it's stronger.

Multicolor: Crystal and mineral- heavy. Multicolor earth dragons commonly become jewelers due to their ability to seed nonmagical crystals such as topaz, garnet, ruby, and emerald. Multicolor earth comes most often from crossing two earth variants.
Brown: Brown earth is heavy in clay, and weighs more per foot than the other colors.
Grey: Heavy in metals, including but not limited to mercury, lead, and bismuth.
Green: Green earth is naturally fertile and promotes growth, it's commonplace for green earth element dragons to be gardeners or farmers. Green earth is also the most common earth variant.

Orange Fire: This is the standard and most common color of fire. It's the original variant and has a balanced temperature.
Red Fire: Red fire is cooler than standard fire but burns for a longer duration. It can appear distinctly pink and comes from fire mixing with ice or water.
Yellow Fire: Yellow fire burns hotter and more erratically than standard fire, with sparks flying. It's less common and results from fire mixing with electricity.
Blue Fire: Blue fire, ranging from teal to sky blue, is the second hottest variant. It's not excessively rare and is associated with pure and powerful fire lineages.
Green Fire: Colder than blue but hotter than its redder counterparts, green fire is linked to dark magic. It occurs when a fire dragon mixes with a dark dragon and is quite rare due to its association with dark ancestry.
Purple Fire: Purple fire is believed to be the hottest flame, but little is known about it. It's thought to come from the purest and most powerful fire lineages or dragons chosen by the Ancestors for important tasks.
White Fire: White Fire is the purest form of fire. It burns hotter than purple fire. White fire nearly crosses into being a plasma, and is regarded as the most powerful form of pure fire.

Dark Blue: Dark Blue water is a standard variant of water, being more saline and dense than standard blue water.
Blue: Standard blue water, this is the normal variant of water, and the most common.
Grey: Grey water is highly pressurized and scalding, having a high er temperature than the others.
Clear: Clear water is regarded as the purest form of water, containing no impurities.
Murky: Murky water is from crossing with earth. It may contain minerals and other impurities- and it tends to be heavy in clay.
