Yellow Background Generator
Make a yellow background or yellow wallpaper in 10 styles. Two are drawn only for yellow: lemon dots, with whole lemons in staggered rows, and paint drips running down from a band of wet paint. 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 yellows, from pastel yellow, butter and lemon to sunshine, golden yellow, mustard, ochre and neon yellow. Every colour stays yellow: each set is checked against one stated range, and so is every pixel of the picture. Set the number of shapes, squares, lemons or drips, 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, lemon, drip, 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 yellow?
Every colour in every set is inside one stated range: hue 46° to 74°, a saturation of 35 % or more and a lightness of 35 % to 92 %. 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 yellow, orange, green or brown?
Yellow. The range starts at a hue of 46°, just after the orange range we use for orange backgrounds (18° to 45°), and stops at 74°, just before the green range (75° to 165°). Dark or greyish yellows read as brown or olive, so the range needs a lightness of 35 % or more and a saturation of 35 % or more. Our tests check, over every colour a screen can show, that no yellow colour falls inside the orange, green, red, pink, blue, purple, brown or gray ranges we use on the other colour pages.
What are the lemon dots and paint drips styles?
Lemon dots are whole lemons (an oval with a little point at each end and a light shine) in staggered rows, one lemon in each cell, each tilted a little by the seed; the number field sets how many lemons fit across, and Angle turns them all. Paint drips are a band of paint along the top with drips running down, each ending in a round drop; the number field sets how many drips.
Which yellows are there?
Lemon yellow, sunshine, canary, butter, mustard, golden yellow, pastel yellow, daffodil, citron, neon yellow and ochre. 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 the tilt of every lemon, where every drip falls and how long it is, 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.
