Syntax Introducedcolorcolor()colorMode()
Red, Green, BlueRGB is a common way to specify
colorMinimum value of number is 0Maximum value of number is 255Resulting in 256 different shades
for each color0 is black, 255 is the specific
color…
Functions that take color as parametersbackground(r,g,b);fill (r,g,b);fill(r,g,b,alpha)stroke(r,g,b);stroke(r,g,b, alpha)alpha is for opaque/transparency0 – entirely transparent255 – entirely opaque
Example1 (size 100X100)
background(129,130,87);noStroke();fill(174,221,60);rect(17,17,66,66);
Example2
background(129,130,87);noFill();strokeWeight(4);Stroke(174,221,60);rect(19,19,62,62);
Example 3: transparency
background(116,193,206);noStroke();fill(129,130,87,102); // more transparentrect(20,20,30,60);fill(129,130,87,204); // less transparentrect(50,20,30,60);
Example 4
background(0);noStroke();fill(242,204,47,160); // yellowellipse(47,36,64,64);fill(174,221,60,160); // greenellipse(90,47,64,64);fill(116,193,206,160); // blueellipse(57,79,64,64);
color object
color(gray);color(gray,alpha);color ruby= color(211,24,24,160);color pink = color(237,159,176);background(pink);noStroke();fill(ruby);rect(35,0,20,200);
SummaryWe studied the usage of color
and transparency
We will not cover other color mode HSB (Hue, Saturation, Brightness)
