I found gwt example for color picker. For example here is one link : http://www.subshell.com/en/subshell/blog/Implementing-a-Color-Picker-Dialog-With-Canvas-and-GWT100.html. But I want color picker something like below image :
How to develop this type of color picker in GWT. In GWT is tit possible to develop this type of color picker? Or is there any better way to develop this type of color picker?
Please help.
You already have half of the solution as per the shared link. Think of your custom color picker as a panel consisting of 2X2 grid and a button panel in bottom. Your 2X2 grid contains 4 panels:
Basic colors: Buttons of fixed colors
Subshell color picker
Custom colors: Button of custom colors
Add to custom colors: Input fields to take RGB & other values
Can you integrate some javascript and HTML5 in this? If you can this tutorial was amazing for me to develop my website's one by using the canevas. Check it out

I am looking for changing colors of an illustration svg in flutter. I tried flutter_svg package but it support applying only one color to the svg and if I do that svg will be displayed as a single color svg, individual colors are lost. Is there any way to change colors at runtime in flutter for a multi color svg?
Do you mean something like this? I call it SVG colorization.
I'll try to squeeze the concept into a short summary. In an SVG file, you need to play around with the fill property as it defines the hex color code.
In terms of programming, you would:
Extract the SVG file data as a String variable svgCode.
Assign the previous hex color code in previousColor & the currently selected hex color code in newColor.
Apply the String.replaceAll method on svgCode to replace the colors.
Update the value of the previousColor.
A more brief elaboration would be
/// Initially without any color selection.
SVGPicture.string('''<svg code with fill #f7ebcb>''');
/// After the user selects the red color.
SVGPicture.string('''<svg code with fill #FF0000>''');
This tutorial can help to solve your issue. Not only does this app changes the color on runtime, but it also allows the user to download the manipulated SVG code.
I began to work with Unity3D since one month and I'm trying to do an application which contains a menu, composed by a panel and several buttons. At this moment, I'm trying to customize the menu, I change the fill color of the panel and buttons, but until now I could not change the border color of the buttons. There is any way to customize the border's color of the UI buttons? I would appreciate your help. :)
The easiest way to add an outline to your button is to use the Outline component (doc).
Simply add the Outline component where your button image or text is. Then configure it how you like it :)
The above results in the following button:
No, you can not change just border color. If you use default buttons, take a look at Source image. It is basically a grey square with black borders. So when you change color of image black color remains black.
To customize buttons as you want you need either create nested UI elements:
or create sprites with colors you want and replace source image
I find nested UI elements to be the easiest way to do something like this. Simple example:
Start out by creating a panel and change the scale until you get the desired size for your button. This will be your "borders".
Next create another panel as a child of the panel you just made and change the scale to be just slightly smaller than your first panel and change the color.
In the Inspector for your panel, add component and type in Button and add it as a component.
Finally, add a text as a child of your panel for a label and you're done.
I am using the colorPicker for a widget:
Now i dont want to show the shades of the color and want to add custom colors.

Please help.
Here's a starting point for implementing a color picker in AEM.
There's also a color palette picker example here that could provide inspiration.
I'm using of Richfaces to implement the color picker function in a Web App, but it doesn't show any text box field to enter RGB manually, pick color using pointer is the only way to choose color. Anyone knows what the issue is?
Fyi, I'm using Richfaces 3.3.3.
It should be like this: http://livedemo.exadel.com/richfaces-demo/richfaces/colorPicker.jsf?c=colorPicker
But in my app, it only shows this:
Is it possible to change the color of text in a Facebook like button? Besides selecting a different color scheme, I don't see a way to adjust the font...
Facebook retains control over their button and only allows you to set predefined options for skinning it. As font color goes, you can choose the light colorscheme to go with light backgrounds, or the dark colorscheme to go with dark backgrounds.
http://developers.facebook.com/docs/reference/plugins/like-box/
YES
It can be done
NO
It's probably not allowed by Facebook's brand guidelines.
Demonstration
I created a demo page that lets you pick the colors using a slider or palette, or that lets you manipulate the filter directly.
Background information
The technique basically works by applying a hue-rotate filter to the element containing the i-frame. Hue-rotate sort-of rotates a color wheel. As such we can't give the button any color we want. We are limited to the 360 degrees of rotation we can apply to the default button. But there are some greens, browns, reds, pink and even purple we can play with. Try it out for yourself.

Include data-colorscheme="light/dark" according to your background in the div with class "fb-like". Light color scheme is for light background and vice-versa.
Facebook has not released this feature yet. However, you may change it using javascript - when using the JS based version, not iframe.
