I don’t know if they are called color strips in the US. I mean the small paper pictures with color samples on. What are your experiences when it comes to the color on the strip and the color you get after painting with that color. Do they always match after the paint is dry?
No
That was a short answer [:D] Is there anything to do about it?
See… I can do short answers [:-^]
Now for the long one…
As far as I can tell you have four factors in any colour match.
- Your eyes. I heard something on radio 4 this week about providing people with coloured plastic strips, printing on coloured paper or even (once the right colour is known) providing them with coloured specs to help them read. This is an educational thing. Apparently the difference in colour that can make a significant difference is less than 1/6 of the colour difference the eye can identify.
SO THIS COULD BE IMPORTANT FOR ANYONE’S KID’S LEARNING DEVELOPMENT.
From our point of view it means that there is an incredible range of minute differences that we can or can’t detect. this will vary with the time of day and how tired our eyes are…
SO IMPORTANT BIT HERE IS…
if it looks right at one time and rubbish at another
IT COULD BE YOUR EYES CHANGING during the day (or under different conditions)
so don’t pull your hair out / ru***o repaint the model.
- Pigments in paint are
(a) in suspension… so exactly what goes on between the paint pot and the finished product will vary according to how well you mix/stir the paint, how you apply it, the conditions while it dries AND THEN the conditions it lives in/under.
(b) not stable… or at least not uniformly stable… so if the model is painted in one make of paint and you add what appears to be the exact same colour when dry made by someone else… then the differnt reactions of the two paints over time MAY produce different colours.
I have a Stewart F3 ABBA C&NW set which stood on display with no colour change for months. It then spent 2 years back in the boxe
WHEW, good answer Dave, by the way we call those colour strips color chips where I’m from. Kind of like the what the English call "fish and chips we call a fish plate, I think!!!
What we call a fishplate you call a rail bar… kind of hard to eat
Talking of which… 06.00 this morning as the air turned blue 'cos of rubbish I fell over working in the cess (the -supposed to be- maintained bit outside the 4 foot way… before the space to the fence [lineside])… I found a fishplate bolt which is about 1" thick… with a 1/2" distortion (like a caterpillar at maximum hump) in it from the loads being pushed through the rail bar by trains breaking heavily on that bit of track. I would guess that its colleagues all sheared… there was no sign of them. Broken plates aren’t common but do occur at that location. (broken plates are usually caused by vertical movement - bad joint support). You can tell by the shape that this bolt took loads from along the rail.
Um, I think i’ve wandered again…[sigh]
