About this tool
Rain-season palettes of slate, teal and wet green, with a solver that gives the exact scrim opacity headline text needs over a photo.
The Monsoon India Palette Generator builds six-role rain-season palettes — sky, rain slate, water teal, wet green, wet earth and a paper tone — and then solves the problem monsoon campaigns actually hit: type over a photograph. For an assumed mean photo tone it steps a scrim's opacity one percent at a time and reports the lowest value at which the headline reaches 3:1, 4.5:1 and 7:1 under the WCAG 2.x contrast formula, compositing with the standard source-over rule. It is meant for designers producing seasonal sale creatives, travel campaigns, editorial covers and app banners where the artwork is a rain photo and the text still has to be readable.

Instead of nudging an opacity slider by eye, you get the exact percentage that reaches each WCAG threshold.
Where a pairing cannot reach the target at any opacity, the tool says so rather than returning a flattering number.
Mood, hue rotation and variation fully determine the palette, so the same brief always produces the same hex codes.
It depends entirely on how bright the photo is behind the words. White text over a mid-tone street photo may need only a few percent of black, while the same text over a bright overcast sky typically needs around 40% to reach 4.5:1, and over half that again to reach 7:1. Measure the region the text actually sits on rather than the whole image.
Cool hues between roughly 150 and 230 degrees: slate blues for cloud, deep teals for standing water, and saturated wet greens for soaked foliage — with one warm earth note, usually a terracotta or ochre, to stop the set going lifeless. Saturation rises and lightness drops as the season deepens, which is why the deep monsoon mood here is darker than first rain.
Yes. SC 1.4.3 makes no exception for photographic backgrounds, and the ratio is measured against whatever pixels sit behind the glyphs. Since a photo varies across its area, the safe approach is to test the brightest patch under the text, or to add a scrim, a gradient or a solid plate so the effective background is predictable.
Usually, because it darkens the text area without flattening the whole image. The catch is that the ratio then varies across the headline, so check the lightest end of the gradient, not the average. The percentages here describe a flat scrim; treat them as the minimum your gradient must reach where the text sits.
