Which term refers to the 216 colors that display consistently across major web browsers?

• A. Hue
• B. Value
• C. Spectrum
• D. Web Safe Colors

Answer: (D)

Web-safe colors are a fixed palette designed so colors look the same across different browsers and systems, especially on older displays with limited color support. The 216 colors come from combining six levels for each RGB channel (00, 33, 66, 99, CC, FF), producing a 6x6x6 cube of colors. Using this set helped avoid color shifts when pages were viewed on various platforms, making the appearance more predictable across major browsers. Hue, value, and spectrum describe general color properties or ranges, not a specific cross‑browser palette, so they don’t refer to this standardized set.
