i need to set a gradient color depending of the percentage value of the bar. For example: -10% light grey 40% grey 70% dark grey...etc increasing grey for example, i insert a picture of what i want: enter image description here

If the light is set to Red, and I want to modify the brightness.
But the Color Model(rgb or hsb) isn't support the brightness.same with color tempreature.
What should I do? Need to change to White light Model, then adjust the brightness?
So, you want to change the color and brightness both. If that is what you want to do then you have to implement two separate variables for brightness and color. The brightness cannot be controlled using just rgb or hsv, it uses separate variable and it ranges from 0-100.

I've noticed a strange behavior with the color picker. When I pick any color from the basic colors (predefined colors), the button's color (the one of the html input element) is changed accordingly.
However, when picking any other color from the the gradient color picker, the button's color won't change. It will stay white. (Note: Don't pick a basic color first or refresh the jsbin page first if you're going to test it)
But... when I first pick a basic color and press OK and then pick a color from the gradient color picker, the button's color will change.
(Tested with Chrome 69)

Test it:

var i = 0;
var inp=document.createElement("input");
inp.type = 'color';
inp.id = 'colo_'+i;
inp.value = '#ffffff';
inp.className = 'datafield';
document.body.appendChild(inp);
It's not actually an error, when you set a color picker to pure white or pure black the luminosity is adjusted to give you the desired color. When you pick a swatch the luminosity is changed to that swatch so it seems like it wasn't working before, but in fact it was working and if you adjusted the luminosity you'd see the color change correctly. You might want to consider a different starting color other than pure black or pure white.
Can I change the color of the shape?
It the shape that I have generated as polygon
I tried
crt 1[
set shape "myPoligon" ;works
set heading 0 ;works
set size 10 ;works
set color red ;doesn`t work
]
Check out the shapes manual: https://ccl.northwestern.edu/netlogo/docs/shapes.html#colors
Basically, when designing shapes you can use any color the shape editor provides. Below the color grid you will find a chooser named "Color that changes:". Here you define a color value, that adjusts according to the color variable of the turtle. All other colors of your shape will not change. By default the color "Gray" is selected. That means all "Gray" polygons and lines of your shape will not be displayed gray. Instead the color is defined by the color variable of the turtle. You can also verify this with the preview shapes at the bottom of the shape editor. They switch colors automatically and indicate areas of your shape that can be changed by setting the color variable of a turtle.
I'm getting gradient colored lines over the chart.
How can I bring them to single color?
It sounds like you have a measure in your color shelf; remove the measure from the shelf, and then set a color for the lines. This part of the Desktop User Guide explains the marks card
I have this image:
I want to convert this to black and white at small increments, the strange thing is that it just disappears after one increment.
For this line
bw_normal = im2bw(img, 0.33);
I get this:
But for this line:
bw_normal = im2bw(img, 0.32);
The word disappears entirely, this shouldn't happen right? It only happens with this image, any other image will continue to show up until 0.1.
This is what I get at 0.32
Just a white space, can anyone please explain this.
im2bw converts the image to a binary (black/white) image. It does this by comparing all pixels' luminance component to the threshold value you provide as the second argument. If the pixel is brigther, it is made white, if it's darker, it is made black.
In your case, the image has only one color (pretty much). This color has a luminance component between 0.32 and 0.33, so if you use 0.33 as threshold, most of the colored portion of the image will be below the threshold and be made black. If you use 0.32, however, most if not all of the image will be above the threshold and thus be made white.
What you experience is expected behavior since your image is basically white background and a single color for the foreground. Once your "increment" reaches that color's luminance, your image is gone.
