颜色选择
目录
想着自己的 logo, 头像, 甚至是一些网站都应该有一个颜色. 所以做一些研究挑选一下.
logo/头像
考量点
- 颜色来源于 这个设计师推荐的颜色
- 适配主题. 现代系统通常有明暗两种主题色.
- 不要用纯白/深灰/浅灰. 容易和背景色重合. 不要用纯黑, 黑底白字难以辨认.
- 暗色主题:
- 选择同颜色的浅色系, 暗色主题不适合高饱和的颜色/深色系. 例如错误提示不要用纯红, 应该 +40% 透明白色, 变成类似于粉红的效果. 或者紫色的渐变图, 浅色可以选 500, 深色选 200
- 所以只有
#57ACDC
蓝色,#57DCBE
蓝绿色,#60C689
绿色符合浅色要求 - 其中蓝绿色在白色背景对比度不够, 淘汰.
- 蓝色和绿色对比
- 蓝色和青色有点接近/歧义.
#57ACDC
在 谷歌颜色选择器 是 400 色深, 而#60C689
色深是 300. 在白色背景中区别不大, 但是暗色主题中个人感觉更好- 人眼对绿色更敏感, 更容易辨认. 比如红绿灯没有蓝灯. 因为绿色很常见, 所以人眼对绿色适应能力强, 不容易引起疲劳. 眼睛/显示器等设备有很多滤蓝光
- 在 rgb 模型中绿色
#00FF00
的亮度值相对较高,而蓝色#0000FF
的亮度值相对较低. 所以绿色对比度更高. - AI 数据也都更推荐绿色
对比效果
用 gpt 做了几个界面对比效果.

最终选择
- 选择了绿底黑字.
- 渐变白字的字母在黑色背景下有点刺眼, 白色背景又不够突出
- 渐变黑字的背景色类似青色, 沟通中会有歧义.
编辑 UI
- 一些文字编辑的界面,白色或者浅色背景才能让人产生「在纸张上书写」的感觉
