"What do you wa- Oh! Sorry kid, didn't see you were white! Let me swallow that baseball bat you're hiding in your pants to make up for it." It's good to be a BWC Shota
Honestly I feel like it depends on not only the situation (lighting, background, environment etc.) but also what position the subject is in and what they're doing. Personally I usually prefer red tattoos but sometimes blue tats just look better
In this case, blue, because it is the color of this character, which can be seen in the example of her costume from the anime, if we talk in general, then it is worth adopting the same principle, making tattoos of the same color as the color of the character, if the color for some reason is not suitable, then it is worth doing the color is lighter or darker. With this choice of tattoo color, we adjust to the main color of the character and make the tattoo more "authentic", or neutral colors such as black, white or gray can be used for tattoos.
