不同颜色代表不同的地形。
绿色是平原;再深一些的掠色和褐色表示高原和更高的山地;而白色则代表终年积雪的雪峰。
红黄绿色的地方表示陆地;绿的地方海拔低,黄较高一些,红更高,红的地方出现白色表示一年四季有冰川积雪。
蓝白色的地方表示海洋;白色的地方海水浅;越蓝的地方海水越深。
地形图指的是地表起伏形态和地理位置、形状在水平面上的投影图。具体来讲,将地面上的地物和地貌按水平投影的方法(沿铅垂线方向投影到水平面上),并按一定的比例尺缩绘到图纸上,这种图称为地形图。

分层设色地形图
分层设色以地貌等高线为依据,应用颜色的饱和度和亮度变换、按不同高程带的自然象征色设色,来表现地貌形态和高度分布的特征,这是中小比例尺一览性地图常用的表现形式。在等高线地形图上,以一定次序的颜色、色调的变化来显示地势的起伏,这样的地图就是分层设色地形图。
分层设色地形图的立体感强,它既能表示海拔,又能表示相对高度,所以它既能表示地势,又能在一定程度上表示各种地形类型。分层设色地形图上各种颜色表示的高度范围,可以查看图上所附的等高线分层设色表。
分层设色通用的颜色顺序是:海洋用蓝色,平原用绿色,低山丘陵用黄色,山地和高原用棕褐色浅紫色表示积雪、冰川。在不同的等深线之间,用分层设色法着上深浅不同的蓝色,可以用来表示海底的深度。
在不同的等高线之间,绿色越浓,表示地势越低;棕褐色越深,表示地势越高;雪线以上的地区通常用白色表示。
自然设色一般采用不同色相,并运用颜色的深浅层次与地貌的高度变化相对应。图面具有明快、美观、造型立体的效应,从而达到一目了然、清晰易读的客观效果。

中国地图中的颜色是为了将相邻省或者直辖市颜色不同,便于区分。
有一个理论说:边界相邻的多边体,如果每一块用一种颜色表示,那么无论有多少块,只要有5种颜色,就能保证相邻的多边体不会出现颜色相同的情况。所以在地图上,地区的中国的世界的,都是用不超过5种颜色来区分不同地域。
地图的4中颜色是为了不同省或者直辖市的区分,看起来方便,没有任何特殊意义!
