One of the most useful tools for a practising artist is a personal colour chart of all the pastels in his/her collection - leaving room for additions either by hue or tonal value.
The next most useful tool is a set of manufacturers' colour charts. These will allow you to see the full range of colours available, and also permit you to preselect pastel sticks before sending your hard-earned money into the ether.
Most manufacturers provide a colour chart online - either a pdf document or a set of jpeg images. Some makers will provide a printed chart, with or without an online version; the posher ones will do a handmade chart - at a price.
I am listing here the major pastel makers, with a web address for their colour chart pages. Apologies to any that I have still left out. You may email me for inclusion.
I missed out on Blue Earth pastels in the original post, so I am adding them here.
Blue Earth Pastels are available in 10 boxed sets, each consisting of 21 individual sticks, organized by hue, value and intensity. Six of the boxes represent the warm and cool side of the primary colors and three boxes are devoted to the secondary colors. Each contains the pure color hue represented in six values from light to dark and 12 grayed variations. The tenth box is composed of warm and cool grays, warm and cool whites, and black.
Here is the Blue Earth colour chart.
The website is http://www.blueearthpastels.com/ and the pastels are available from Dakota Art Pastels.
Henri Roché Pastels provides ten magnificent charts provided on their website.
Pastels Henri ROCHÉ are currently available in 650 colours.A colour chart is available as 10 jpeg images, as a pdf nuancier, or as a hand-made colour-chart of 648 nuances for 240 euros. http://www.lamaisondupastel.com/shop/shop_classic.php?langue=en

Swiss manufacturers Caran d'Ache have just (April 2012) launched a range of pastel "cubes" (square sticks) and pencils in a range of 84 colours, to complement one another. The colour chart may be saved as a pdf at http://www.pastels.carandache.com/pdf/nuancier_pastels_pencils_cubes_carandache.pdf

Back to France. Pastels Girault has 300 colors, although they are aiming for a range of 526.
Currently these colours are graded by theme into four sets: Portrait, Landscape’ Flowers/Fruit, Background. Click on each colour to see it at sidebar - they cannot be downloaded. The whole website needs a makeover. It seems stuck in the same time warp as the French Pastel Society used to be before it escaped! Roché Pastels currently has the coolest website - it was designed by Antoine Leblond, son of pastellist Camille Leblond.
Artisan Pastellier in Albi, France: Didier Boinnard's shop is in the historic centre of the city, at 5 Rue Puech Berenguier. His products are based on vegetable dyes, including Isatis tinctoria - woad, or pastel in French!

The sets are also available as portrait or landscape selections. The catalogue is available as a pdf download and the pastels are available via mail order on line.
Terry Ludwig has a 515 colour pastel line. Only hand made charts are available at 40 dollars each - I don't know if that is per set, or for all 515. No charts are visible on line, so I have not given the web address - it is easy to find with a search engine.
Diane Townsend has three lines of pastel - softform, terrages, and thin line. You can download a jpeg image of the collections - boxed sets, not a chart.
There are sets of all 120 Solid pure colors, 120 Light (L) and 120 Dark (D) variations of each color and 48 exotic colors set (10 fluorescent, 7 iridescent, 15 pearlescent and 16 metallic). That comes to 408 in total.

A handmade chart is available from supplier for 25 dollars.On the website the colurs are present as sets of 3 to six shades ( there are 11 greys) and these must be saved individually; you can also right click between the colours and choose the print option.

Finally, from the United Kingdom, Unison Pastels.
There are nearly 400 colours ranging from subtle greys and earth colours to brilliant reds, blues, greens and yellows. The pastels are supplied in Mixed, Portrait and Landscape colours in boxes of 8, 18, 36 and 72 colours, but are also available individually.
The colour charts are available only on screen – they cannot be downloaded except, curiously, as individual colours – have fun! The best you can do is download the image of the half-stick set of 63, on http://www.unisoncolour.co.uk/colours.aspx?Group=half%20stick%20sets&Page=half%20stick%2063%20set
You can email the manufacturer for a printed version. Of course, you can always use the Prt Sc button on your PC and paste the image into Photoshop or some such program and save it as a jpeg. The result is not too bad - I can't post it here for copyright reasons; just be aware that Unison point out that the online colour is approximate, and of course it will depend on your PC's colour card and monitor.
