George Washington 3p stamps - color identification help

here are another half dozen to offer  some form  of comparison  -  regret I'm unable to say what the colour was supposed to have been initially since I don't have Scott or any U.S.  catalogue, but whatever the catalogues do state there's no doubt this 'pink' appears as a pale image in terms of colour, and poor centring looks to have been commonplace.        I've refrained from editing in any form, so what you see here is just  how my Leica lens sees these stamps in ordinary daylight.     IMHO there appears  almost no difference  in  colour strength between  these  and the  first batch posted,  though it's  possible  these  may  show a  slight improvement  in  sharpness of  image. 

Hi, thanks for reply... i meant the outer frame line at top and botom, which distiguishes type1 from other types (and sorry, just noticed...it was typo, mine is type1) ...about second pic i agree, unfortunatelly i dont have scaner at the moment and using phone... Took a picture on a day ligth and tried to insert all in one pic to compare shades easier. So, thats best i could do...

Hi Terri - cranking up the colour to accentuate the differences appears to have worked here, and agree with your suggestion that the left two appear brownish with the others now appearing more pink. Whether there's a risk of misleading ourselves with this bit of methodology may be a possibility - the degree of shade variation seems a God-sent piece of fun for some folk who love to name the slightest of differences.
I think SG have recently re-issued their Colour Guide - my copy is dated 1969 and sold for five shillings (£0.25p), just prior to the U.K. going decimal.
This colour guide lists, and shows, one hundred named shades/tints based around primary colours and amongst a variety of advice SG offer - when comparing our stamps with their guide - is " .......... comparison should be made in a good North light. (Sunshine is not good). If artificial light must be used, good fluorescent lighting is the best substitute for daylight" - not really sure what North light is, presumably it implies we should avoid the the direct glare as the sun arcs from east, through south, then settling in the west? The suggested way of using this guide is by means of a black card (supplied with the kit) which has a pair of small holes little over 1" apart. Through one you view the stamp in question, and through the other the chosen colour range - presumably adjusting the latter until you see the chart colour that most clearly matches your stamp.
No idea if any other publishers of stamp catalogues have issued anything similar.
All this is to overlook those factors that affect colour, such as sunlight, moisture, heat, so perhaps unreliable for the majority of used stamps that have been soaked and haven't led sheltered lives, all of  which detract from whatever the original colour was - then there's the issue of dodgy eyesight for some of us older kids.

P.S.  thanks for improving the look of my stamps - perhaps they're worth more now.
