### p5.js version
2.3.0
### Web browser and version
browser independent, tested on Safari Version 26.5 (21624.2.5.11.4)
### Operating system
MacOS
### Steps to reproduce this
setting the `colorMode()` to anything other than RGB doesn't seem to affect [lerpColor](https://beta.p5js.org/reference/p5/lerpColor/). This used to work in previous p5 versions and the documentation reads:
The way that colors are interpolated depends on the current [colorMode()](https://beta.p5js.org/reference/p5/colorMode/).
expected (p5.js 1.x):
<img width="643" height="329" alt="Image" src="https://github.com/user-attachments/assets/26fdc930-4ea7-4a81-8f1e-834ef2944149" />
actual result (p5.js 2.x):
<img width="507" height="344" alt="Image" src="https://github.com/user-attachments/assets/f294a01a-d8b9-4a4b-9cac-5821e5648164" />
### Steps:
1. Copy the code snippet into a p5.js 2.0+ version
2. Compare result with running the code in p5.js 1.x
### Snippet:
```js
function setup() {
createCanvas(100, 100);
background(200);
// Create p5.Color objects to interpolate between.
let from = color(218, 165, 32);
let to = color(72, 61, 139);
colorMode(HSB)
// Create intermediate colors.
let interA = lerpColor(from, to, 0.33);
let interB = lerpColor(from, to, 0.66);
// Draw the left rectangle.
noStroke();
fill(from);
rect(10, 20, 20, 60);
// Draw the left-center rectangle.
fill(interA);
rect(30, 20, 20, 60);
// Draw the right-center rectangle.
fill(interB);
rect(50, 20, 20, 60);
// Draw the right rectangle.
fill(to);
rect(70, 20, 20, 60);
describe(
'Four rectangles. From left to right, the rectangles are tan, brown, brownish purple, and purple.'
);
}
```
