Teal Background Generator
Make a teal background or teal wallpaper in 10 styles. Two are drawn only for teal: an agate slice, with wavy bands round a pale crystal hollow, and sea glass, with rounded frosted pieces that never touch. The other eight are a gradient, soft clouds, a checkerboard, grid paper, marble, paper, soft blobs and polka dots. Pick one of 11 sets of teals, from duck egg, robin egg and mint teal to turquoise, lagoon, aqua, classic teal, peacock teal, deep teal and deep sea. Every colour stays teal: each set is checked against one stated range, and so is every pixel of the picture. Set the number of shapes, squares, bands or pieces, the angle, the softness and the grain. Every picture comes from a seed number: the same seed and size always give the same picture, and New seed gives you a new one. Choose desktop, 4K, phone, a 16:9 video-call background, tablet, square, banner or your own size up to 4096 pixels, then download a PNG or JPG, or a PDF to print. Nothing is uploaded.

Frequently asked questions
Is this a photo?
No. Every gradient, agate band, piece of sea glass, check, line, vein, cloud, blob and dot is drawn by our own code from the seed: it is artwork, not a photograph.
How do you make sure it stays teal?
Every colour in every set is inside one stated range: hue 166° to 194°, a saturation of 25 % or more and a lightness of 10 % to 90 %. The drawing only blends colours from the chosen set, which all share one hue, and darkens very slightly for grain, which keeps the hue. Our tests check all 55 colours, and every pixel of every preset, against that range.
Is it teal, green or blue?
Teal, the blue-greens in between. The range starts at a hue of 166°, just after the green range we use for green backgrounds (75° to 165°), and stops at 194°, just before the blue range (195° to 250°). Turquoise and aqua sit inside it. Our tests check, over every colour a screen can show, that no teal colour falls inside the green, blue, purple, pink, red, orange, yellow, brown or gray ranges we use on the other colour pages.
What are the agate slice and sea glass styles?
Agate slice is a cut stone seen face on: wavy bands round a pale crystal hollow, a thin light line between bands and a dark rind outside; the number field sets how many bands, and every ray from the middle crosses them in order. Sea glass is rounded frosted pieces with a soft shadow, a paler middle and a small shine, scattered so that no two pieces touch; the number field sets how many pieces.
Which teals are there?
Classic teal, turquoise, lagoon, aqua, deep teal, mint teal, peacock teal, duck egg, verdigris, deep sea and robin egg. The table below gives the five colours of each set as hex codes.
Can I use it as a video-call background?
Yes. Choose Video call background (16:9, 1920 × 1080), download the PNG or JPG and pick it as a virtual background in your video-call app.
What does the seed do?
It fixes where the agate centre sits and how its bands wave, where every piece of sea glass lies and its shape, and where every cloud, blob and fibre goes. The same seed and size give exactly the same picture, pixel for pixel.
Is it free?
Yes. There is no sign-up, no watermark and no limit.
Is anything uploaded?
No. Every pixel is worked out by JavaScript in your browser. Nothing is sent anywhere or saved when you close the page.
