Mustard is not quiet yellow, it is however a shade of yellow that is dull or dark. It resembles culinary mustard. So, mustard is the colour of the sauce you get on your favourite street or kiosk hot dog.
Mustard is the perfect alternative to yellow for people who don’t like to wear yellow because it is too bright. Because mustard is a darker shade of yellow, it suits all skin tone. In fact, I can say that you do not need to wear tan before you wear mustard.
