For example light at 2000K-3500K looks more orangeyellow and is called ultra warm or warm white and as temperature increases in Kelvin color changes to more of a paper white known as natural or neutral white between 3500K and 5100K and finally into a bluish-white.
Light bulb color scale. The higher the Kelvin number the whiter or bluer the light. Color Temperature Lighting Design Lab. Energy Used is how many watts this light bulb uses.

The scale runs from 0-100 and those lights with a CRI closer to 100 have the ability to show truer colors across a wider spectrum. 5000K is a cool color with a blue hue. Household fixtures are commonly found in color temperatures on the Kelvin scale of 2700K warm incandescent 3000K warm white halogen and 3500K household fluorescent.
Most residential lighting applications fall somewhere on the scale between 2000K and 4500K. For reference candlelight has a colour temperature of about 2000K while sunlight has a. The two most common light bulb colors are.
