CSS/HTML色見本
色の基礎知識
ディスプレイに表示される色は、RGBすなわち光の三原色(赤:Red, 緑:Green, 青:Blue)
の各要素の大きさで表すことができます。
平たく言いますと絵の具を混ぜる要領で色を作りだすことができるのです。
たとえば赤100%、緑0%、青100%の配分で組み合わせると紫色になるといった具合です。
色の指定方法
CSSで色を指定するには、以下の５通りの方法があります。
| 値（赤を表した例） | 説明 |
|---|---|
| #f00 |
#と3つの文字(16進数)で色を示します。
16進数とは0～15間での数値を1文字で表したものです。 |
| #ff0000 |
#と6つの文字(16進数)で色を示します。
2桁の16進数の場合は、0～255までの値を表すことができます。 |
| rgb(255, 0, 0); | rgbという文字に続く括弧中に、RGBの各要素に対応する0～255までの数字をカンマで区切って指定します。 |
| rgb(100%, 0%, 0%) |
rgbという文字に続く括弧中に、RGBの各要素に対応する0～100%までの割合をカンマで区切って指定します。 この値は小数点第一位まで指定することが可能です。 |
| red |
色の名前で指定します。 大文字、小文字はどちらでも構いません。 どのような名前が使用可能かは後述します。 |
