Lighting For Fish Colour

At present, the sun is shining on the front of one of my tanks. This is a fairly rare occurrence, apart from the obvious need for the sun to be shining (rare enough!), in winter it never reaches the right position before it sets and in  a few weeks the leaves will be on the trees which will block the sun. What strikes me is how colourful the fish look in the sunlight compared to usual. I'm not sure how much of this is down to the light coming from the front rather than above and how much is due to the wider spectrum of sunlight.

As I'm (slowly and carefully) preparing to convert my tanks to LED strip lighting, I'm now wondering about adding some extra coloured strips at the same time. I'm not interested in a complicated colour-changing system, but in extra lights to enhance the apparent colour of the fish. When one of my old pink-hued tubes went, I replaced it with a white one and there was a definite loss of redness to the ruby barbs, for example. On the other hand, lights with very high colour temperatures are also advertised as enhancing the colours of fish. So what is the best solution? Should I try to cover the widest spectrum possible? Logic tells me that the more red there is in the lights then the more will be reflected from red fish, the same for blue etc. But I might be wrong. I know there are "full spectrum" tubes, but what about LEDs? "White" ones only seem to come in "warm" or "cool" white.

That's good news as cool white (6000 - 6500K) strips are what I've bought so far. I was thinking of perhaps adding a lower powered strip each of red and blue.

A couple of times in the last few months, I found a guide/easy-to-read table of which colours to opt for to enhance the colours of different species of fish. Stupidly, I didn't "bookmark" it and am really struggling to find it now. Will keep hunting, though...

Edited to add: found it - http://www.drsfostersmith.com/media/PDF/ColorSpectrumGuideFW.pdf (link from http://www.liveaquaria.com/PIC/article.cfm?aid=305). Maybe not any good to you, but I was determined to find what I knew I had seen. 

Yes, it is interesting, but these details of wave length of light are only available for the (very expensive) aquarium lights. The cheap LED strips I would use only say "red", "blue" or whatever. Interestingly, the link calls 8000K "warmer white" (compared to the 12000K) whereas with the LED strips 6500K is generally described as "cool white", with "warm white" being as low as 2500K so there is quite a difference between these and the expensive aquarium lights, difficult to compare the two.

At present, I'm probably going to start with 4 strips, 2 cool white, one each of red and blue. The cost of a 5 metre strip (enough for several tanks) is so low that it's easy to experiment and see how things go. I'll start with one tank and let that run for a while before I move on to the others.

The tank I bought which came with LEDs fitted has just 24, 12 I would describe as warm white (slightly yellowish), and 12 of a pinkish colour. It never ceases to amaze me how well the plants have grown with such an apparently small number of LEDs and fairly low lighting. The fish, Lemon and Flame tetras, look good as well.

I reckoned it was red and blue that were the most important colours on most fish which is why I thought giving them a bit of a boost would help. When the sun was on one tank yesterday, I particularly noticed that the pearl danios looked much bluer, in the normal tank light they are just silvery. Many fish seem to have a blue glimmer under the correct lighting. And even fish which are not themselves red often have partially red fins which stand out, examples of mine being the Green Tiger barbs, Lemon tetras and X-ray tetras.
