css에는 3가지 새로운 색상 모드가 추가되었습니다. 1. "rgba(255,0,0,0.5)"와 같은 RGB 모드에 알파 투명도를 추가하는 RGBA 모드 2. "hsl( 360)과 같은 HSL 모드 ,50%,50%)"; 3. HSL 모드에 알파 투명도를 추가하는 HSLA 모드.
이 튜토리얼의 운영 환경: Windows 7 시스템, CSS3 버전, Dell G3 컴퓨터.
1. CSS1&2 색상 표현 방식(W3C 표준)
1. 색상명 방식 (색상 키워드를 사용하여 해당 색상을 표현합니다.)
예: red(빨간색), blue( 파란색), 분홍색(핑크)
장점: 특정 색상에 대해 편리하고 빠르고 정확합니다.
단점:
제한된 색상 수를 나타냅니다.
투명 색상을 지원하지 않습니다.
2. HEX 모드 16진수 모드(16진수를 사용하여 색상 표현)
Syntax:
#RRGGBB 或 #RGB
값:
RR: 빨간색 값입니다. 16진수 양의 정수
GG: 녹색 값입니다. 16진수 양의 정수
BB: 파란색 값. 16진수 양의 정수
값 범위: 00-FF
예: #FF0000 빨간색 #FFFF00 노란색. #FF0000红色 #FFFF00 黄色。
优点：表示颜色种类多，使用较方便
缺点：
16进制单位换算很成问题
不支持透明颜色。
特定颜色需要工具配合或者一定的颜色调配知识
3、RGB方式 三原色配色方式
语法：
RGB(R,G,B)
取值：
R： 红色值。正整数 | 百分数
G： 绿色值。正整数 | 百分数
B： 蓝色值。正整数 | 百分数
取值范围:0~255或者0%~100%
例如：rgb(255,0,0)红色 rgb(255,255,0)黄色
优点：表示颜色种类多，使用较方便
缺点：
不支持透明颜色
特定颜色需要工具配合或者一定的颜色调配知识
二、CSS3 新增颜色表示方式
1、RGBA模式
此色彩模式与RGB相同，只是在RGB模式上新增了Alpha透明度。
语法：
RGBA(R,G,B,A)
取值：
R： 红色值。正整数 | 百分数
G： 绿色值。正整数 | 百分数
B： 蓝色值。正整数 | 百分数
A： Alpha透明度。取值0~1之间。
例如:rgba(255,0,0,0.5)半透明红色
46d5fe1c7617e3914f214aaf043f4ccf
body{background:rgba(255,0,0,1)}
div{width:300px;
height:300px;
background:rgba(0,0,255,0.4);
position:absolute;
top:0;
left:0;
}

36cc49f0c466276486e50c850b7e4956
2、HSL模式(色轮模式没有透明度)
语法:
HSL(H,S,L)
取值：
H： Hue(色调)。–0(或360)表示红色，120表示绿色，240表示蓝色，也可取其他数值来指定颜色。取值为：0 - 360
S： Saturation(饱和度)。取值为：0.0% - 100.0%
L： Lightness(亮度)。取值为：0.0% - 100.0%
例如:hsl(360,50%,50%) 红色
46d5fe1c7617e3914f214aaf043f4ccf
body{background:rgba(0,0,255,0.5);}
div{width:300px;
height:300px;
background:hsl(140,50%,50%);
position:absolute;
top:0;
left:0;
}

36cc49f0c466276486e50c850b7e4956
3、HSLA模式(色轮模式有透明度)
语法:
HSLA(H,S,L,A)
取值：
H： Hue(色调)。–0(或360)表示红色，120表示绿色，240表示蓝色，也可取其他数值来指定颜色。取值为：0 - 360
S： Saturation(饱和度)。取值为：0.0% - 100.0%
L： Lightness(亮度)。取值为：0.0% - 100.0%
A： Alpha透明度。取值0~1之间。
例如：hsl(360,50%,50%,0.5
투명 색상은 지원하지 않습니다. 특정 색상에는 도구 조정 또는 특정 색상 혼합 지식이 필요합니다
3. RGB 방식 3원색 매칭 방식
