How do you build a professional UI colour system?
UI in the modern world In design, colour is not just decoration, but a central carrier of information hierarchy, brand identity and user interaction. A good colour system should be consistent, accessible and extended. However, many designers often face problems of “colour mismatch” or “colour grade insufficiency” during the initial stages.
From single base colour to full colour scale
The first step in building the colour system is to identify the brand colour. Color）。 But just one color is not enough. You need a series of steps. Shades addresses the shadows of suspension, background colour, border and depth. Our tools use the science-based colour mix algorithm from 50 to 900 automatically generate 10 levels of colour for you:
- 50 - 100： Usually used for very light background colours or small area partitions.
- 400 - 600： Core brand area for key components such as buttons, progress bars, etc.
- 700 - 900： Dark-coloured steps for text, for dark-coloured states after suspension, or for background in dark-colour mode.
The importance of semantic colour
Besides branding, UI systems must also contain semantic Colors. They represent a specific meaning:
- ● Success（Success）： For submitting positive feedback, such as success, validation and pass.
- ● Warning (Warning): is not an error.
- ● Error（Error）： For dangerous signals such as error reporting, system anomalies, etc. on forms.
Through our Color Palette. Generator, you can automatically match the most harmonious semantic color with the brand color, ensuring the whole UI. High degree of visual uniformity, rather than abruptly inserting unrelated red and green lights.
Addressing accessibility challenges
A beautiful, unreadable design is a failure. WCAG（Web Content accessibility guide) requires that there be sufficient contrast between text and context. When you generate palettes, we automatically judge whether the label text is white or black, depending on the colour brightness of Luminance. This helps developers avoid low contrast design traps at the coding stage.
Why do you choose auto-generated rather than manual pick-up?
Manually moving in the colour picker to find the colour steps often results in uneven leaps in colour saturation, resulting in a whole set of steps that look "dirty" or "scramble". Algorithms generate to ensure that the color is in A linear smooth transition in space in HSL (chromatic, saturation, brightness) which is extremely UI-seeking The project of quality is of crucial importance.
