When preparing dozens of images for web publishing, which color mode should be used to ensure web compatibility?

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

Answer: (D)

Web content is displayed by screens that mix red, green, and blue light, so saving images in RGB ensures the color data matches how monitors reproduce colors. This alignment helps your photos and graphics look consistent across different browsers and devices, especially when you also use the common sRGB profile for broad compatibility. CMYK is intended for print and can shift colors when viewed on a screen. Grayscale strips out color, which isn’t suitable for most web images that rely on color. Index color uses a limited palette, which can cause banding and color loss in photographs. So, using RGB color mode is the best choice for web publishing.
