Short answer
Coloured stage and event light removes parts of the spectrum, so any colour that depends on the missing wavelengths darkens or shifts: red lipstick under blue light turns almost black, and pale pinks take on the colour of the light. Bright, distant stage lighting also flattens the face, which is why stage make-up is stronger than everyday make-up. Checking colour under the actual lighting is the only reliable test.
A red lip, a green dress or a pink cheek looks that colour because it reflects those wavelengths more than others. If the light falling on it contains little of them, there is nothing to reflect. A deep blue gel or a blue LED wash contains very little red, so a red lipstick has almost nothing to return and reads as dark or near-black; under a red wash, red and white can look almost the same. Theatre make-up references put it bluntly — saturated red light makes all but the darker flesh tones virtually disappear, and green light greys flesh tones and rouge. The environments pillar explains how gels and LED fixtures build stage colour; this page is about what that does to the person being lit.
Stage lighting is bright and often comes from the front and above, which fills in the shadows that normally show the shape of a face. The audience is also far away. Together these flatten features and wash out subtle colour. Stage make-up compensates by strengthening lightness contrast — highlighting the bones that stand out and shading the hollows — and by using stronger lip and eye colour than would look natural up close. The same principle applies, less strongly, to speakers on a lit stage at a conference or a wedding: a little more definition than usual reads as normal from the audience.
Weddings, parties and venues increasingly use coloured LED uplighting — often purple, blue or magenta — to set a mood. Those fixtures mix a few narrow-band emitters, so even their 'white' can render colours oddly. Guests' clothes and make-up take on the room's colour: pastels almost disappear into it, reds and oranges darken under blue and purple washes, and skin loses its warmth. Photographs make this worse, because the camera does not adapt as the eye does and may try to correct the colour cast, pushing skin in unexpected directions. The fashion events pages cover outfit choices for specific occasions.
Neutral and strongly saturated clothing colours survive coloured light better than subtle mid-tones and pastels.
Costume designers test colours under the show's lights because nothing else predicts the result. For an ordinary event the equivalent is simple: ask what lighting the venue uses, look at photographs from previous events there, or view the outfit and make-up under a similar coloured light at home — many smart bulbs can produce comparable colours. Neutral, deeper and clearer colours tend to hold up; for make-up, matte finishes avoid flare from bright spots. These are editorial suggestions, not rules; the decision rests on what the wearer prefers.
Why: Blue or purple uplighting contains little red light for the lipstick to reflect.
Fix: Expect it under those washes; a lighter, warmer lip or photos taken in white light near the entrance avoid it.
Why: Pastels reflect most wavelengths, so they show the colour of whatever light hits them.
Fix: View the outfit under similar coloured light beforehand, or accept that it will read as the room's colour.
Why: Strong frontal light fills the shadows that normally define the face.
Fix: Add more definition than usual — contour, stronger brows and lips — judged from a distance under the stage light.
Each statement is labelled by kind — established fact, a standard’s requirement, observed market data, a convention, or Colourwise’s own interpretation or analysis — with the strength of the evidence behind it.
ConventionModerate evidence
Stage lighting and audience distance wash out facial features, and stage make-up compensates with stronger definition; saturated coloured stage light changes how make-up colours read, with red light making all but darker flesh tones virtually disappear.
Caveat: Describes theatrical practice drawn from standard make-up texts; the size of effects depends on the specific lights.

FactStrong evidence
Coloured and white LED light can be produced by mixing a few narrow-band emitters, such as red, green and blue, rather than by a continuous spectrum.
Source: LED Basics
FactStrong evidence
A surface can only reflect wavelengths present in the light falling on it, so a red lip or garment lit by light containing little red appears dark.

Colourwise interpretationLimited evidence
For events with coloured lighting, neutral and clearly saturated colours are likely to hold up better than pastels and subtle mid-tones; this is offered as an editorial suggestion.
Based on: Colourwise's application of spectral reflectance under narrow-band light: pastels reflect broadly and take on the light's colour, while strong colours retain their contrast in some washes.
Caveat: Depends on the specific wash; a saturated colour lit by light lacking its wavelengths still darkens.
