Anyway, the thing with colour blocking is that it's not as easy at it looks. You can't just take everything in your wardrobe that doesn't match with anything else & pair it together. There are rules & guidelines (I know right...who would've thought?). Some people are just born with an innate knack for this stuff but for the rest of us, there's science & a very helpful tool is this little colour wheel thingy below:
You can make the following combos using the color wheel as your guide:
1. Colors directly next to each other (i.e. yellow and yellow-orange; yellow and yellow-green; violet and blue-violet, etc.)
2. Colors that form right (90 degree) angles with each other (i.e. yellow and red-orange; blue and violet-red; green and orange, etc.)
3. Colors directly across from each other (i.e. yellow and violet; blue and orange; red and green, etc.)
4. Colors that form a T (i.e. blue, orange, and violet-red; yellow, violet, and red-orange; yellow, blue-green, and red-orange, etc.)
5. Colors that form an X (i.e. blue, orange, violet-red, and yellow, violet, blue-green, and red-orange, etc.)
2. Colors that form right (90 degree) angles with each other (i.e. yellow and red-orange; blue and violet-red; green and orange, etc.)
3. Colors directly across from each other (i.e. yellow and violet; blue and orange; red and green, etc.)
4. Colors that form a T (i.e. blue, orange, and violet-red; yellow, violet, and red-orange; yellow, blue-green, and red-orange, etc.)
5. Colors that form an X (i.e. blue, orange, violet-red, and yellow, violet, blue-green, and red-orange, etc.)
Brown is a neutral along with white, black & denim blues so they will go with pretty much anything.
Hope that helps!
