Which has higher contrast, white characters on a red background or gold characters on a red background?

Banners with white characters on a red background have high contrast. Contrast refers to the degree of brightness or color difference between different areas in an image. In a banner with white characters on a red background, there is a great brightness contrast between the red background and the white font, which makes the font stand out. In the banner with gold characters on the red background, the brightness difference between the red background and the gold font is small, and the contrast is low, which makes the gold font on the red background difficult to identify. Therefore, from the perspective of contrast, banners with white characters on a red background have higher contrast.
