-Subtractive color is how we see color in paints. It is the result of light either bouncing off or being absorbed by an object due to what is known as pigmentation. The light which bounces off the object is translated by our eyes and brain into the perception of color.

This means that objects do not have an inherent color. The color of an object is the result of light and pigmentation.

For example, an apple is not red because it is inherently red. It is red because it is reflecting red light wavelengths and absorbing the rest.

In art, the subtractive primary colors are red, blue and yellow. Primary colors are colors which, in theory, are able to mix all other colors in the visible spectrum. Below is a color wheel which uses red, blue and yellow primary colors.

Primary Colors: Red, blue and yellow
Secondary Colors: Orange, green and violet

Graphic design merupakan seni atau kemahiran dalam menggabungkan teks dan gambar dalam sesuatu iklan, majalah atau buku. Graphic design terbahagi kepada dua iaitu GRAPHIC dan DESIGN

Graphic - merupakan Visual yang berkait  dengan seni, imaginasi dan ekspresi yang melibatkan dalam banyak medium seperti melukis, mewarna dan banyak lagi. Graphic juga merupakan elemen visual. Elemen visual yang terdapat dalam Graphic Design ialah Garis, Warna, Bentuk, Tekstur, Ruang, Rupa dan Typography. Dengan menggunakan asas Elemen Visual kita dapat membentuk sesuatu Idea

Design- Untuk membuat pilihan dalam Rupa dan Kegunaan dalam sesuatu benda sebelum ia di-cipta/direka. Jadi Design merupkan Berfikir, Penyelesaian Masalah, Pratikaliti. Dalam Graphic design terdapat peraturan yang boleh dipertimbangkan. Peraturan ini dikenali sebagai “The Principles Of Design”. Semua peraturan ini berkait antara satu sama lain.

The primary colors of light are different from the primary subtractive colors of our paints. Below is an additive color wheel which illustrates what happens when you mix colored lights together.
-Primary Colors of Light: Red, green and blue
Secondary Colors of Light: Cyan, magenta and yellow

If you mix green with red light, you get yellow light. If you mix blue with green light, you get cyan light. If you mix blue with red light, you get magenta light.

When you mix (add) all the colors of light together, you get white light. This is why it is referred to as additive color. With subtractive color, you see color because some wavelengths are being reflected and others are being absorbed (subtracted). When you mix all the subtractive colors together, you do not get white light; you get mud.

Vector images have some important advantages over bitmap images. Vector images tend to be smaller than bitmap images. That’s because a bitmap image has to store color information for each individual pixel that forms the image. A vector image just has to store the mathematical formulas that make up the image, which take up less space.
