**Explanation:**

When you mix white with red, you get the color pink. Let's understand why this happens.

**Understanding colors:**
Colors can be classified into two categories: additive and subtractive colors.

1. **Additive colors:** Additive colors are created by mixing different colors of light. When you combine red, green, and blue light in different intensities, you get a wide range of colors. The primary additive colors are red, green, and blue (RGB).

2. **Subtractive colors:** Subtractive colors are created by mixing different colors of pigments or dyes. When you mix different pigments together, they absorb certain wavelengths of light and reflect others, resulting in a specific color. The primary subtractive colors are cyan, magenta, and yellow (CMY).

**Mixing white and red:**
When you mix white with red, you are mixing a subtractive color (red) with an additive color (white).

1. The color white is the presence of all colors in the additive color model (RGB). It represents the combination of red, green, and blue light at full intensity. When all three primary colors are mixed in equal proportions, they form white light.

2. The color red is a primary subtractive color in the subtractive color model (CMY). It reflects red light and absorbs other colors.

**Resulting color:**
When you mix white (additive color) with red (subtractive color), the red pigment absorbs all colors except red, while the white light combines with red light. This combination results in a lighter shade of red, which is commonly known as pink.

Therefore, when you mix white with red, you get the color pink.
