Aqua Lullaby leads · Bottle Glass Dark supports
The lead is the date whose color has the stronger contrast against dark ink, so the stationery has a text-safe surface. Hue distance between the two dates: 44°.

Two colors, one hierarchy
The hard part of a two-color wedding palette is not finding the colors; it is deciding which one leads. Two colors at equal weight produce a tie, and a tie reads as indecision on a table, a invitation and a photograph. The tool computes the hue distance between the two dates and suggests a lead, but the couple's preference should win over the suggestion.
A practical hierarchy is one lead color, one supporting color and a neutral. The lead appears on the stationery, the flowers and the largest textile; the support appears on ribbons, candles and the second flower; the neutral is the linen, the paper and the room. The second birthday's color does not have to appear at full strength - a tint is often the better supporting role.
What the blend actually is
The tool mixes the two hex values at 50 percent per channel and prints the result. That is a real color, not a metaphor: it is the midpoint in RGB, which is close to but not identical with the midpoint in a perceptual color space. It is useful as a neutral or a third accent, and it is rarely the right lead.
The blend is also a good sanity check. If the midpoint is muddy, the two colors are far apart in a way that will be hard to reconcile; if it is pleasant, the pair has a shared undertone. Either way, the blend is a fact about the two values, not a verdict on the couple.
Where the palette meets the room
Lighting changes a palette more than most planning guides admit. A warm tungsten room pushes every color toward yellow; daylight pushes it toward blue; a phone photo at the reception is usually warmer than the room looked. Choose the palette in the light where the event will actually happen, and look at the flowers under that light, not only in the shop.
For an evening event, deep colors read darker than the swatch and pale colors read brighter near a window. The site's palette includes a full range, so the practical move is to test the two or three candidate colors as fabric swatches on the table, under the venue's lights, before committing to stationery.
Stationery, flowers and attire
Stationery is where the hex values are most useful: the printer can match a value, and the paper stock decides how saturated it looks. Ask for a proof on the actual paper. Flowers are the opposite: a florist matches a family, not a hex, and the same flower varies by season and grower. Send a photo and a range, not a value, and accept the variation as part of the material.
Attire is the place to stop matching. Asking guests or the wedding party to wear an exact color produces a row of slightly different versions of it, and it puts a cost on people who do not own the color. A dress code that names a family - "earth tones", "soft greens" - is easier to follow and photographs better than a hex.
The contrast question
Wedding stationery carries names, times and addresses at small sizes, so 4.5:1 is the ratio to aim for on the paper, not just on the screen. If the lead color is pale, the names belong in the dark ink and the color belongs in a border, a monogram or a large numeral. If the lead is deep, the light ink works, but check the printed proof - uncoated paper can eat the contrast.
The tool prints the measured pairings for both dates and the blend, so the stationery decision can start from numbers. It cannot measure the venue's lighting or the paper's absorption; those need a proof and a visit.
A palette that survives the day
The palette is a tool for repetition, not a rule for every object. Two or three strong repeats - the invitation, the table runner, the flowers - are enough. Everything else can be neutral, and the neutral is what makes the repeats visible.
Finally, leave room for the things the couple did not plan: a gift wrapped in a different color, a guest in a bright dress, a sunset during the portraits. A good palette frames those moments; it does not compete with them.
The order of decisions
Decide in the order the constraints arrive. First the venue and the light, because they cannot be changed cheaply. Then the lead color, then the support, then the neutral, then the paper, then the flowers, then the attire. Stationery is printed after the palette is settled; flowers are ordered after the palette is settled; attire is a suggestion, not a match. Reversing the order is how couples end up with invitations that cannot be reprinted in time.
The second birthday's color does not need equal area. Give it a tint on the cake, a ribbon, a small print on the menu, or a signature drink; let the lead carry the stationery and the largest textile. The tool computes the blend and the hue distance, which helps you describe the pair to a florist or a printer, but it does not decide the proportion. A useful default is roughly 60 percent lead, 30 percent neutral and 10 percent support, with the second date's color inside that ten percent if it is strong.
Photographs will not preserve the palette exactly. Daylight, tungsten, candlelight and a phone's automatic white balance each move the colors, and a reception often mixes all four. Tell the photographer which two colors matter most and ask for a few frames in neutral light; accept that the album is a record of the evening, not a swatch book. The palette's job is to make the room cohere in person, and the photographs will carry the memory even when the hue drifts.
Questions
How does the tool pick the lead color?
It computes the hue distance between the two dates and suggests the one with the stronger contrast against the site's inks. The suggestion is a starting point; the couple's preference decides.
Is the blend a real color I can print?
Yes. It is the midpoint of the two hex values in RGB, printed as a hex value. Like any screen color, it needs a proof before a print run.
Should the wedding party wear the exact colors?
Usually not. Exact-color dress codes are hard to follow and expensive for guests. Naming a color family is more practical and photographs better.
