THE TEN MOST ASK QUESTIONS HERE @ LUCID COLOUR...

 

1. DOES MY SCREEN NEED CALIBRATION BEFORE CHOOSING PIGMENTS & COLOUR PRODUCTS?

No... We all know your personal eye sees colour slightly different to every other individual person, the human eye and brain is complex and also personally unique. Computer screens and software can project or transmit colour different to each individual system or set up.

The best way to get the exact colour that you need is to invest $5 for a swatch card or $5 colour jar sample or $20 for a colour chip with data.

Then you have the visual and technical colour data in your hand, and we know that a colour sample and full colour data is more valuable than a few dollars and definitely more accurate to you or your own clients eye then the representation of physical colour on a screen.

 

If you like Yes more then no... We can give you the tools to get the difference (Delta E = ΔE) between our screen input, your screen input and your individual eye to the sample. This can give you a colour match down to ΔE 0.4 [cie L*a*b*]  (Most colour industries set a minimum of ΔE 1.0 units [cie L*a*b] or  0.1% in cie X*Y*Z  co-ords).

 

As a second option we can send a sample of the colour and/or a colour swatch for you to undertake your own spectral analysis via equipment + software and your eye under the correct lighting.

This is how you can achieve an exact colour match to a point of two samples can not be determined as different and seen by the eye to be the same. Yes sometimes the term colour match is used incorrectly,

20 shades off is just that 20 shades off or a Delta ΔE of 2.0+ units can be seen by the human eye but many will say that is a colour match!

 

The photo below is one of many colour tools and this example is the Gretag Macbeth Color Checker used by X-rite & Pantone companies for colour calibration software systems, used with our spectrograph equipment we can get colour variations down to Delta ΔE 0.1 units.
