Which color mode should be used for images intended for the web to maintain color fidelity?

• A. RGB color mode
• B. CMYK color mode
• C. Indexed color
• D. Grayscale

Answer: (A)

Images for the web should be in RGB color mode because displays render colors by combining red, green, and blue light, so the RGB model directly matches how screens show colors. This alignment helps preserve color fidelity when images are viewed in browsers. CMYK is designed for printing with ink and can look off on screens since it uses a different color system. Indexed color limits you to a fixed palette of 256 colors, which can cause banding and loss of subtle tones. Grayscale removes color information entirely, so it can’t represent full-color scenes accurately on the web. For best results, use RGB (ideally with an sRGB profile) to maintain consistent colors across devices and browsers.
