Default Colour Lightfastness

Wonder if anyone knows where I can find the colour lightfastness rating for various brands online. Colour Pencil Associatiion of America(CPSA for short) published their 6th version of the Handbook but it is available to members only. The reason I am asking is bcs I am currently using student grade watercolour pencils. To my horror I found that 1 of my Mother's Day card that was put at a shop to sell, the colour faded to almost nothing. Mother's Day cards are not popular where I stay and that card must have been exposed to sunlight all day through without being looked at. It was just 3 weeks.

Does anyone know which brand has good lightfastness, can endure the tropical sun? I was looking at Caran d'Ache and Derwent but not sure how good these 2 are in terms of lightfastness.

Some companies publish a Materials Safety Data Sheet (MSDS) on their websites and some of these have lightfastness on them. Often it is just a case of contacting the company via email and asking directly.

Some lightfastness can be retained by heat embossing the image - if this helps.

Tropical sun will be a problem with almost anything, I would think. Also, even within a range of products, some pigments are more lightfast than others, so it's not simply a case of finding a good range. I know that in artist's quality watercolours the ratings vary from A to (if I remember right) D, and that was just in one brand. In some ways I'd have thought there might be less of a problem with student quality because more of the pigments will be synthetic rather than natural.

I think Caran d'ache Luminance pencils have the highest lightfastness rating, and they are one of the most expensive colored pencils. However, I think it would be a better idea to look into protecting your cards with either a sealant spray, or maybe clear bags that offer UV protection. I don't actually know if these items exist, but it might be something to look into.

Derwent publishes the lightfastness for each of their product ranges as well: Derwent Pencils | Products - Derwent - Inktense Pencils

Most pencils should provide these ratings on their sites. Hth!

Thanks ladies. Read in Gary Greene's book that Caran d'Ache Luminance is 100% lightfast. Silver, gold and pink have always been the colours I look out for in any box set I buy. Can anyone confirm if Golden Bismuthyellow is equavilant to gold? I can't tell from their colour chart.
