How to assign random colors to multiple objects

I’m trying to write a code which draws a circle at each of a series of coordinates given from a csv file.
I want to give each circle a random color but my code at present gives the same color to all the circles.
How can I achieve what I want?!
// takes xy coordinates of and draws a circle at each point

Table table;

void setup() {

  table = loadTable("xyloc.csv", "header");
  size(1400, 600);

  for (TableRow row : table.rows()) {

    int x = row.getInt("x");
    int y = row.getInt("y");
    fill(random(255), random(255), random(255));
    ellipse(x/5, y/5, 2, 2);

Hi @jimjimmer,

Welcome to the forum! :wink:

No problem, just hit the </> button when editing a message or use triple backticks ``` around your code like this: ``` code ``` → code

Your code should work since the random() function is giving a random result each time its called (by definition). Therefore your ellipses should be filled with a random color.

Check this code (similar to yours):

void setup() {
  size(500, 500);

void draw() {
  float rx = random(width);
  float ry = random(height);
  fill(random(255), random(255), random(255));
  circle(rx, ry, 50);


Ha what a ditz yes it does work doesn’t it ! My circles were too small on the screen and I couldn’t see the variation! Thanks ever so much I’m sure I will be back soon!

That’s it, 2 pixels large is quite small! :wink:

Have fun programming :yum:
