Acid turns it in red, while base will turn it blue.
Adding phenolphthalein indicator to hydrochloric acid (HCl) will turn it red in basic solutions.
Acids turn universal indicator solution red.
Acids turn red/pink when red cabbage indicator is added. Alkali/bases turn blue/green. Neutrals turn purple.
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.

Knuckles is the red Echidna in sonic x
There is no red hedgehog in Sonic the Hedgehog. You either mean Knuckles the echidna, the second player Sonic from Colors and several bootleg games, or a sonic fan character. Shadow is a black hedgehog with red markings, but he's probably not who you saw.
He is a red echidna.
Knuckles the edcidna.
Knuckles the Echidna's favorite color is traditionally portrayed as red. This color choice is likely due to his association with the Master Emerald, which is also red in color. In various Sonic the Hedgehog media, Knuckles is consistently depicted wearing red shoes and gloves, further reinforcing his affinity for the color red.

Use only knuckles. Give it only red chaos drives AND only red food and power type animals. Reincarnate it seven times. Then you have a knuckles chao.
