Kuler notes
Kuler is an Adobe Labs colour palette generator and explorer. You can use the Flash-based app to
either create your own colour scheme by setting your own hex values or you can search through,
rate, and tag, and comment on the schemes that have already been created by others. All the
colour schemes can then be downloaded in the Adobe Swatch Exchange (.ASE) format which
works with any of Adobe’s Creative Suite applications.

Colour Hunter
Colour Hunter is a colour palette generator that uses flickr photos to create a palette. To find
colour palettes on Colour Hunter, enter a search term in the box at the top of the page. You can
search by tag or hex colour code or the image URL from flickr’s Web site. If you have an image
that you saved on your computer, you can upload it and get a colour palette generated based on
the colours in the image. You can also use Colour Hunter to search by tag.
Colour palette Generator

The Colour Palette Generator is a simple tool that also lets you use a photo from the Web as the
inspiration. It is a bit more basic than Colour Hunter, above, but sometimes that’s just what you
need. Just enter in the photo’s URL from any place on the Web and the generator will create a
colour scheme based on the photo.

ColourJack
ColourJack is an online generator that lets you hover over a colour on the site’s grid to see themes
that use that colour. You can select which format you want to see your colour scheme in (hsv,
rgb, or hex) and you can then export it to Illustrator, Photoshop, or ColourJack Studio. Other
ColourJack tools include the Colour Sphere and the Colour Galaxy, which provide alternative
UIs for generating colour schemes. A Mac OSX widget is also available.
Daily Colour scheme

Daily Colour Scheme is an “everyday colour resource” that provides you with the colour schemes
used by other websites like 9Rules, for example, using those sites as inspiration, you can bookmark
their schemes, download them in your preferred format, or import the schemes into your design
program like Photoshop, Illustrator, or Top style. There are many more colour palettes available
which are used to create the effective palettes.
4.7 image file formats

Choosing the right file format to save your images is of vital importance. There are three image
formats in constant use on the net—GIF, JPG and PNG. Each is suited to a specific type of image,
and matching your image to the correct format should result in a small, fast-loading graphic.
Saving and exporting into these formats will require a decent image editor.
4.7.1 Graphics interchange format (Gif)

CompuServe’s 8-bit GIF format has long been the most popular, mainly because of its small size.
It is ideal for small navigational icons and simple diagrams and illustrations where accuracy is
required, or graphics with large blocks of a single colour. The format is lossless, meaning it does
not get blurry or messy. The GIFs use a simple technique called LZW compression to reduce the
filesizes of images by finding repeated patterns of pixels, but this compression never degrades
the image quality.
GIF files can be saved with a maximum of 256 colours: This makes it a poor format for
photographic images. Since this can sometimes be tight, GIFs have the option to dither, and will
mix pixels of two different available colours to create a suggestion of another colour.
