* A true blue dye job? This would likely be a very dramatic look and might not work well with brown hair, depending on the shade of brown.
* A blue rinse? This would be a more subtle blue tone and might be a good way to add some cool tones to brown hair, but it could also make it look dull or ashy.
* Blue highlights or streaks? This could be a fun way to add some color and dimension to brown hair, but it's important to choose a blue that complements your skin tone.
Here are some things to consider:
* Your skin tone: If you have warm skin tones, a cool blue might clash. If you have cool skin tones, a blue dye could look great!
* Your hair color: A darker brown will be harder to see blue in compared to a lighter brown.
* The intensity of the blue: A darker blue will be more noticeable, while a lighter blue will be more subtle.
Ultimately, the best way to know if blue Kool-Aid would look good in your brown hair is to experiment! You could try a temporary color spray or even just a blue hair chalk to see how it looks. You could also ask a hairstylist for their professional opinion.
