# [Gimp-user] Question about the meanings of the numbers in a color gradient

```I've almost got it figured out.

```
```
Third row is how many segments. If an example has 2 segments it is 2; if an example has 18 segments it is 18. This one has 6 segments so it is 6.
```
```
First three columns are left point, right (end point), and point where the gradient changes - and if the blended colors are close where it is doesn't matter. Next are the left color in RGB decimal. Following is a number that I don't know what it represents, and probably it is maximum at 1.000000. Following is the rgb code for the right color, then the number that I don't know what it means. Following that are four 0's I understand noone knows what they mean but leave them alone.
```
```
Now, I can't get the gradient editor to work, but I did get it and the foreground color picker to help me select numbers.
```
```
There are two numbered scales, such that the maximum is 100. One is blackness, "V", and it controls how dark the color is. The other is the saturation; it controls how intense my color is. It goes from 0 to 100.
```
```
Somehow at one point I got the opacity slider to display; not sure how I managed it, but it controlled the opacity number and nothing else.
```
```
Now, in the gradient editor, I get the position at wherever my mouse is at, the rgb color, HSV, and luminance and opacity.
```HSV is 0.0  some number between 1 and 100 100.0
Luminance is some number between 0 and 100.

```
It seems that everything changes together, except opacity and blackness, which change separately.
```
```
If I carefully keep the black control all the way down and change the saturation, both the luminance and the middle number in HSV change.
```
```
I don't see anything that goes from 0 to 1.000 that affects luminosity, saturation, or anything that controls how light or intense the color is.
```
```
So say I want RGB color 1.0, .307, .307, with the middle HSV number 69.4, and luminance 45.1; and in the foreground color picker this is Hue 0, saturation 85, V=100 (0 blackness), RGB = 255 38 38, and the HTML notation is ff2626. What number do I want to put after the RGB colors where 1.000 is now?
```
```
Feel free to point me to anything that explains it that is written in English and won't take more than fifteen minutes for someone who got this far to figure out, and also if there is a chart or, better, tool somewhere that will just tell me what numbers to use for the colors and saturation I want.
```
```
If I wanted to change the opacity, would that be changed IN the gradient, or would it be changed with how one applies the gradient?
```
Thanks!

Yours,
Dora Smith

Hi darxus,

```
```http://www.chaosreigns.com/code/dl/Gay-flag.ggr

I just made it, based on the colors from
https://en.wikipedia.org/wiki/Rainbow_flag_(LGBT_movement)
```
```
we've discussed the best name for the gradient - 'gay flag' as such
seems to be imprecise.

I think using the names as in
https://en.wikipedia.org/wiki/LGBT_symbols#Flag_gallery is a good choice
- and thus we could use Rainbow flag.

```
```I'm pretty confident it's perfect.
```

The color of the left and right end point of the red stripe are slightly
different - is this intended?

Overall, the colors you have used are different to the HTML notation
used on the Wikipedia page - it uses color keywords. They are also
different to the colors of the six-color flag shown there.

I'm not sure if exact matches matter, but still would be curious how you
did get the colors you've used.

If we add the flag gradient for the symbol it represents, we might want
to consider to add gradients for a few other flags from the gallery
linked previously, and use the names provided there.

In regard to including gradients at all:

We've had a few gradients for national flags in releases in the past
(French, German, Mexican, Romanian). They do still exist in our code
repository, but have been marked as obsolete:

In general, we have reduced the number of resources that come with GIMP
by default. Adding some resources that have a meaning beyond their mere
technical use is interesting to some people, of course.

Adding any of them has the potential to generate a lot of discussion -
I'm fine with that for any gradients resembling any of the flags linked
in the aforementioned gallery, but also a bit less frilled about some of
the discussion that might happen around some religious, political or
national flags.

```
```From a more technical point of few, figuring out the best and fastest
```
```way how to use the possible gradients to create some flags in GIMP - in
particular if the pattern isn't pales or fesses - is an interesting
challenge.
