State true or false
halogens are coloured.

Explanation

**Step-by-Step Solution:**

1. **Identify the Halogens**: The halogens are a group of elements in Group 17 of the periodic table. They include fluorine (F), chlorine (Cl), bromine (Br), and iodine (I).

2. **Understanding Color in Elements**: To determine if halogens are colored, we need to understand that color in elements is often due to their ability to absorb certain wavelengths of light.

3. **Absorption of Light**: Halogens can absorb light in the visible region of the electromagnetic spectrum. This absorption leads to the excitation of electrons from lower energy levels to higher energy levels.

4. **Transmission of Light**: The color that we perceive in halogens is actually the color of the light that is transmitted after some wavelengths are absorbed. The remaining light that is not absorbed gives the halogen its characteristic color.

5. **Conclusion**: Based on the above points, we can conclude that the statement "halogens are colored" is true. This is because they absorb certain wavelengths of light and transmit others, resulting in distinct colors.

**Final Answer**: True, halogens are colored.
