Indoor lighting can come in a variety of colours, which can greatly impact the mood and atmosphere of a room. The most common colours of indoor lighting include:

Warm white: This colour temperature is typically between 2700K and 3000K and creates a warm, cozy atmosphere. It is commonly used in living rooms, bedrooms, and dining rooms.

Cool white: This colour temperature is typically between 3500K and 4100K and creates a bright, energetic atmosphere. It is commonly used in kitchens, bathrooms, and home offices.

Daylight: This colour temperature is typically between 5000K and 6500K and creates a bright, natural light similar to daylight. It is commonly used in spaces where colour accuracy is important, such as art studios, photography studios, and retail stores.

Coloured lighting: Indoor lighting can also come in a range of colours, such as red, blue, green, or purple. These colours can be used to create a specific mood or ambiance in a room, or to highlight specific features or objects.

It's important to consider the colour of indoor lighting when designing a lighting scheme for a space, as it can greatly impact the look and feel of the room.
