1 Luminance contrast ratio

Luminance contrast ratio is a numerical value that compares the relative brightness of two colors, based on how the human eye perceives them. The higher the ratio, the more contrast there is between the colors. The Web Content Accessibility Guidelines (WCAG) recommend a minimum luminance contrast ratio of 4.5:1 for normal text, and 3:1 for large text, to ensure readability for people with vision impairments. You can use online tools like WebAIM Contrast Checker to calculate the luminance contrast ratio of your text and background colors.

Pretty simple: 1. Black over white: pass. 2. White over black: okayish. 3. Any other combination: go to hell. 4. There is no "but".

2 Color contrast

Color contrast is a measure of how different two colors are in terms of hue, saturation, and lightness. Color contrast can affect the mood, tone, and harmony of your content, as well as its accessibility. For example, using complementary colors (opposite on the color wheel) can create a vibrant and dynamic contrast, while using analogous colors (adjacent on the color wheel) can create a soothing and harmonious contrast. However, too much or too little color contrast can also cause eye strain, confusion, or boredom for your audience. You can use online tools like Adobe Color to explore and adjust the color contrast of your palette.

Uma dica é sempre adotar uma cor que n?o seja extremo - nem branco, nem preto absolutos - para o texto dos seus conteúdos. O contraste absoluto (verde/violeta, azul/laranja, amarelo/roxo também s?o ruins). Quando o contraste é grande há uma rejei??o, e a leitura é, cognitivamente, algo já "n?o natural". A chance da pessoa instintivamente rejeitar o texto é grande. Prefira tons de cinza bem escuro ou bem claro. Se for usar cor, aumente a grossura da fonte e garanta que o fundo n?o seja uma cor diretamente oposta. Isso vai trazer leveza para a escrita. Confira o livro "Frida kahlo e as cores da vida" e veja o efeito que uma fonte azul em papel amanteigado tem - é quase um carinho na vista.

3 Size contrast

Size contrast is a measure of how different two elements are in terms of their dimensions, such as width, height, and depth. Size contrast can help you create hierarchy, focus, and balance in your content, by making some elements more prominent and others more subtle. For example, using a large headline and a small subheading can create a strong size contrast that draws attention to the main message, while using a medium-sized image and a medium-sized caption can create a moderate size contrast that supports the visual content. You can use online tools like Figma or Sketch to design and test the size contrast of your elements.

4 Shape contrast

Shape contrast is a measure of how different two elements are in terms of their form, such as round, square, or irregular. Shape contrast can help you create variety, interest, and meaning in your content, by making some elements more distinctive and others more consistent. For example, using a circular logo and a rectangular banner can create a high shape contrast that highlights the brand identity, while using a square grid and a square button can create a low shape contrast that reinforces the layout structure. You can use online tools like Canva or Illustrator to create and modify the shape contrast of your elements.

5 Texture contrast

Texture contrast is a measure of how different two elements are in terms of their surface quality, such as smooth, rough, or patterned. Texture contrast can help you create depth, realism, and emotion in your content, by making some elements more tactile and others more flat. For example, using a textured background and a smooth font can create a striking texture contrast that adds dimension and character to the text, while using a flat icon and a flat color can create a minimal texture contrast that simplifies and clarifies the icon. You can use online tools like Photoshop or GIMP to apply and adjust the texture contrast of your elements.

As an artist, I naturally use images to create content regularly. This is a natural process. Images of nature, lifestyle, fashion and style have a strong impact across cultures. I'm not talking copy paste clip art that one used to see as art. I'm talking about using art work created by an artist. It's amazing to me, when I see real art in advertising and marketing. I've actually recommended that to a few companies, and it's catching on.

Specific for digital and mobile, don't forget about white. White space and white lines. You don't only need contrast; you also need 'negative space' to group elements together. Great visual design is using contrast, using white, and designing for light and dark mode on mobile devices.
