According from what I can gather from some research, the color of the Kagune is depenant on the proteins that carries oxygen in the blood, (since blood is mixed in with the kagune to take form...)

To put it in example.

Red blood: Hemogoblin, Bright red. Deoxygenated blood: Dark red.

Blue Blood: Hemocyanin, present in mollusks such as the horseshoe crab, contains a copper-containing protein that results in the blue color. Colorless when oxygated and dark blue when deoxygenated. Usually in the colors of grey-white to pale yellow while inside the body of the mollusk due to living in low-oxygen environments.

Both of these colors has been seen in the ghouls´ kagune from what the anime has shown and the color-combinations could be determined by the balance between Hemogoblin and Hemocyanin in the individual ghoul´s blood... For example...

Yamori: Red on the outside and glowing blue on the inside. combination of both types.

Touka: Bright red. Oxygenated hemoglobin

Tsukiyama: Blue on the outside, red on the inside, in short, deoxygenated cyanin with deoxygenated hemoglobin.

Ayato: Dark Blue, Deoxygenated  hemocyanin

Kaneki: Dark red, Deoxygenated hemoglobin

Nishio: Bright blue: Could be a combo between oxygenated hemoglobin and dexygenated hemocyanin.

Ryouko Feuguchi: Pale yellow on the outside and bright red on the inside. Oxygenated Hemocyanin in majority and mixed with oxygenated hemoglobin. (The same goes for mr. Feuguchi and their daughter Hinami who got both.)

Yoshimura/Owl: Ukaku: Grey-White with additional kagune in dark red. Hemocyanin for the Ukaku and hemoglobin mixed in for the blades and armor.

If this is the case then I suspect that the source for the Hemocyanin in the ghouls´ blood could be the Rc-cells as in the real world, humans don´t have this and in the world of tokyo ghoul then everyone has rc-levels in some degree (200-500 in humans, above that and up to 8000 is ghoul measurements.)

This is just a theory of the source behind the kagune´s colors when active, I could be wrong but considering the realistic tone within the series I would not be surprised if Ishida was the one that gave the studio a color-scheme for the kagune based on some research of blood and its color.

Is this a possible theory?
