What is caused from pairing two high-saturated colors together, even while they may be complementary to one another?

Pairing two high-saturated colors together, even if they are complementary, can cause a visual effect known as "vibrating colors" or "color vibration".

Here are the steps explaining why this happens:

1. High saturation: Colors that are highly saturated are pure and intense. They have not been diluted with white, black, or a neutral color. When two such colors are placed next to each other, they retain their intensity and can appear to compete for attention.

2. Complementary colors: These are colors that are opposite each other on the color wheel. When used together, they can create a vibrant look, especially when used at full saturation. Examples include red and green, blue and orange, or yellow and purple.

3. Vibrating colors: When two highly saturated, complementary colors are placed next to each other, they can create a visual phenomenon known as color vibration. This is where the boundary between the two colors appears to shimmer or vibrate. This happens because the eye struggles to focus on the high contrast between the two colors.

4. Visual discomfort: The effect of vibrating colors can cause visual discomfort or fatigue. It can be disorienting and make it difficult to focus on other elements within the design.

5. Use in design: While color vibration can be uncomfortable, it can also be used intentionally in design to create a certain effect or draw attention. However, it's generally recommended to use it sparingly and consider the impact on the viewer.

In conclusion, pairing two high-saturated colors together, even if they are complementary, can cause a visual effect known as color vibration, which can lead to visual discomfort.
