Purple Screen

A fullscreen purple screen for stage style mood lighting, gaming setups and photo colour effects. Note: a screen cannot emit real ultraviolet, and this page…

Purple has become the default colour of a lit desk , streaming setups, gaming rooms, keyboard backlights, LED strips behind monitors. A full screen purple is the free version of that, and it works because purple is dark enough not to glare and saturated enough to read as deliberate.

Ambient and stream lighting

A second monitor or tablet showing purple, placed out of frame, throws coloured light onto a wall or a subject in the same way a small RGB lamp does. It is soft, because the source is large and flat, and it costs nothing to try before buying hardware. Combined with a warmer colour from another screen , orange or coral , you get the two tone look that most streaming setups are aiming for.

A background that stays out of the way

Purple sits low in luminance compared with the primaries, so a full purple field is much less fatiguing than a bright one. That makes it a practical choice for a secondary display you want lit but not attention grabbing, or for a projector that needs a coloured field between segments.

What this page does not claim

Purple light is sometimes associated with plant growing, because horticultural LEDs often look purple. That appearance comes from mixing deep red and deep blue diodes at specific wavelengths and intensities that plants use for photosynthesis. A display producing a purple that looks similar to the eye is not emitting those wavelengths at anything like the required intensity, and it will not grow anything. Screens are not grow lights.

What this purple screen offers

Violet is the lighter version, magenta the saturated secondary, indigo the deep blue neighbour, and pink the pale one.

Purple screen questions

What is a purple screen used for?

Mostly ambient lighting , a second screen out of frame casting soft coloured light for a stream, a video or a room. It is also a comfortable low brightness background for a display you want lit without it competing for attention.

Can a purple screen be used as a grow light?

No. Grow lights look purple because they combine deep red and deep blue diodes at specific wavelengths and high intensity. A display is producing a visual match at a tiny fraction of the required power. It will not help a plant.

What is the difference between purple and violet here?

Purple on this site is #800080, a dark, evenly balanced red blue mix. Violet is #EE82EE, much lighter and pinker. Both are editable , type any value into the colour box.
