Colorful tabs

barbudo2005

In relation to my Mod "Automatic color for Active tabs & Active tab stacks using favicon" that also gives color to the tab and tab stack depending on the color of the favicon, I wanted to ask you some questions:

https://forum.vivaldi.net/topic/76205/automatic-color-for-active-tabs-active-tab-stacks-using-favicon

1.- Is it necessary to use the setting "Accent from Page"?

2.- How do you get the color of the favicon of the inactive tabs?

@aminought thanks for your work! I think it might be a good idea to upload the normal JS file too and not just the minified one. Then it will be easier for other to understand the code and make adjustments.

@barbudo2005
To be honest, I don't understand where exactly the favicon color is used in your code. As far as I can see, the color needs to be specified manually.

Not yet, but I will add the use of prefs later.
The inactive tab has a regular icon that has filters applied to it in order to make it dim. I just take an icon and generate a palette of colors from it.

@oudstand The mod code is completely open, I used only a minimized version of the library chroma.js to work with color: https://gka.github.io/chroma.js.

@aminought Oh sorry, I didn't look correctly. I just saw the minified chroma file and missed the color_tab.js file.

Only in the inactive tabs. In the active tab is automatic using the code:

#tabs-container  .tab.active

{border: 2.5px var(--colorAccentBg) solid !important;}

@barbudo2005 Sorry, I misunderstood the meaning of "inactive tab". I thought you were referring to unloaded from memory.

That's the magic of javascript. I looked at how Vivaldi generates colors and implemented a similar approach in my own code.

UPD 4/7/2024:

Vivaldi settings now affect the mod:
- Tabs are colored only when the option "Accent from Page" is enabled and "Transparent Background Tabs" is disabled.
- Option "Accent on Window" now works as expected.
- The color saturation is no longer a constant, but is taken from the "Limit Accent Color Saturation" option from the current theme.
- Changing the settings in real time affects the mod.
The color of the tabs of the internal pages no longer depends on the color of the icon.
Fixed bugs with incorrect text color.

@aminought Cool! Thanks for sharing!

I come from a discussion where some people including me are trying to only apply custom colors to certain "separator" tabs. We use local HTML pages with embedded favicons, so your mod seems suited for our goal!

I have a question about JS, which I know nothing about: can your mod be changed to do what it does now but only to the tabs with a certain keyword in the title, or something like that?

ADDENDUM: what if title has also a color_keyword in it? Can JS look up for it and use it to set the color? That way I just open a new tab, search trigger_keyword + color_keyword => the tab colors itself!

aminought

@DavidBevi It's possible, but I'm not sure when I'll be able to find the time for it, sorry. If you're willing to wait about two weeks, I'll add this functionality.

DavidBevi

@aminought Yeah, awesome! Don't worry, don't rush

Your request makes no sense at all.

Alternatives:

1.- A JS script is designed to apply the favicon color for tens of thousands of pages that are visited. That's the case of @aminought who uses the chroma.js file to find the color of the favicon.

2.- In the case of the code I use, it is the script that is in the core of Vivaldi that discovers the color of the favicon and I use the CSS code already mentioned in my post to apply it.

In your case you have 10 or 15 separators in which "you know" the color that you want to apply, therefore it does not make any sense to write a script to "discover" the color that you want to apply based on the name of the HTML file.

To top it off, in the script you would have to write a list of the keywords you want to "discover":

Keyword1: Travels
Keyword2: Work
Keyword2: Family
etc.
etc.
etc.
Keyword15: Music

It is "cheaper" to use the code I mentioned and using copy and paste to make a list with the 10 or 15 codes and replace Title of Page1= Travels and color of Page1 = red in the following code:

.tab:not(.active)[title*="Page1"]
{background-color: color of Page1 !important;}

It takes you a few minutes to do it.

This issue reminds me of the saying "Doing yourself traps in solitaire".

@barbudo2005 Hey, thanks for replying but you made a wrong assuption, I really was looking to build a thing that lets me use all colors, from 000000 to ffffff, so it would require 16 millions blocks of code

I really don't need that much colorspace, but I want a lot of flexibility, and even 8 colors per channel make 500 blocks of code, which seem a bit overkill. I know how to make them quick, but I think it won't be very quick at runtime.

Also, I may have given the impression that I asked for it to be done, but I was just looking if it was possible because I'd like to dip my toes in JS, and maybe having this goal finally gives me the motivation to start studying it.

But you also undermine my motivation, I now get that you have a solution which I may have missed in the other thread because I only read the last page, so I'm going to check it out when I can.

Lastly, you wrote Doing yourself traps in solitaire: Never heard it, can't find it in websearch, mind explaining it? (I'm from Italy)

"Doing yourself traps in solitaire"

If you are playing solitaire with playing cards, it doesn't make much sense to cheat, since you are basically cheating yourself.

A small correction: chroma.js is used only to work with color. I adapted the algorithm for extracting the color from the icon that I found in the obfuscated source code of Vivaldi UI.

barbudo2005

@aminought

Thanks for the clarification, as I was intrigued as to why the setting "Accent from Page" was needed if you were supposed to get the color of the favicon from chroma.js.

So I still have the following question:

How do you get the favicon color from the "source code of Vivaldi UI" for the inactive tabs if the "Accent" colors are only generated for the active tab?

DavidBevi

Update: I made this tool

Demo of separator in action

Working separator: https://davidbevi.github.io/separator/

Info, demo, code: https://github.com/DavidBevi/separator
Also I'm very open to contributions, or just ideas.

I have to admit that I avoided learning JS and instead asked ChatGPT to do it (@barbudo2005 forgive me, for I have cheated myself! ), so I still hope in @aminought's updates (again, no pressure).

barbudo2005

@DavidBevi

I am obliged to inform you that cheat itself together with the use of ChatGPT leads inexorably to senile dementia.

The first symptoms of a decline in understanding are already showing when you mention that you are going to wait for an update from @aminought.

DavidBevi

@barbudo2005 I said "I still hope", I have a feeling that ChatGPT might be able to help me even to tweak @aminought's code

Semi-seriously, I know I did not learn JS by using ChatGPT, but I did a thing. I really struggle with motivation, seeing stuff done is a great boost, so I do it without only doing it.

DavidBevi

I updated my separator (beta v0.2), now it's simpler and supports saving the title and the color inside the URL. https://davidbevi.github.io/separator/

Also, I've edited @aminought's code to only color the separators. INSTALLATION

Put chroma.min.js and color_tabs_bb.js into <YOURVIVALDIDIRECTORY>\Application\<VERSION>\resources\vivaldi.
Add lines into <body> of window.html:

<script src="chroma.min.js"></script>
<script src="color_tabs_bb.js"></script>

Restart Vivaldi.
