HTML Color Picker compared with Adobe Color and Coolors
Seletor de cores HTML	Adobe Color	Refrigeradores
Objetivo principal: Reading and converting a single colour. You pick a colour from a palette image or type a value, then read it as HEX, RGB and HSL for use in HTML and CSS.	Objetivo principal: Building a coordinated scheme from a base colour. The tool is organised around colour rules, not around converting one value between notations.	Objetivo principal: Generating and saving whole palettes. Single value conversion is secondary to browsing and editing a set of colours.
Colour harmony support: Limited to lighter and darker shades of the chosen hue, with links to a shade tool and a colour mixer. There is no harmony rule engine.	Colour harmony support: Offers monochromatic, complementary, analogous, triadic and split-complementary rules applied to a base colour, which suits systematic scheme design.	Colour harmony support: Produces palettes of up to 5 colours on the free plan and up to 10 on Pro. The listed features focus on browsing and editing palettes.
Accessibility checks: No contrast or colour vision checks are listed on the picker page. It only shows sample black and white text on the selected colour.	Accessibility checks: Includes a contrast checker based on WCAG ratios and a preview of the palette under several types of colour blindness.	Accessibility checks: Palette contrast checks are listed as a Pro feature, so they are not part of the free plan.
Conta e custo: The picker page states no price and needs no sign-in. The surrounding site promotes paid plans, courses and certificates.	Conta e custo: Starts with a free sign-up call to action, and palettes can be saved to a personal library for reuse in other creative projects.	Conta e custo: The free plan has no time limit but caps saved palettes at 10 and shows ads. Pro is a paid plan and removes those limits.
Quando escolher: Choose it for a quick notation conversion while writing CSS, with no account and no setup.	Quando escolher: Choose it when you need a rule-based scheme with built-in accessibility checks.	Quando escolher: Choose it when you want to iterate on many palettes and organise them into projects.
