   #F57F17 คือสีแบรนด์ YuuFood (เดียวกับที่ใช้ในเว็บ YuuSupply เดิม)
   แต่ตัวอักษรขาวบนพื้นสีนี้ได้ contrast เพียง 3.2:1 ซึ่งตกมาตรฐาน WCAG AA
   จึงแยกเป็นสองระดับ:
     --brand      เหลืองสด — ใช้เป็นพื้น คู่กับตัวอักษรสีเข้ม (6.5:1)
     --primary    เหลืองเข้ม — ใช้เป็นพื้น คู่กับตัวอักษรสีขาว (5.3:1)
                  และใช้เป็นสีตัวอักษรบนพื้นอ่อน
