| Abstract |
The purpose of the research is to estimate the amount of a color image reaction variation by changing areas in order to design the method to reduce an error about the color sample when it is applied in the real situation.
The summary of the results acquired in this research is as followed.
(1) With fixed observing distance of 1m, we observed that the value and chroma of each color object became higher as sight angle was increased as 2°, 10°, and 30°, even though the variation ratio was different.
(2) With fixed sight angle of 10, we observed that the value and chroma of each color object becane higher as observing distance was changed from 1m to 3.3m, even though the variation ratio was different.
(3) With same area, we observed that the values and chromas of each color object in the conditions of 1m-30° and 3.3m-10° were almost same.
(4) When the area became larger, the subjects tended to feel that colors were bright and clear with the increase of tone. In all the colors, the variation of a color reaction in chroma is higher than those in value.
In future, we can observe the limit in applying to colors in the architecture by identifying the tendency of the color change according to the area change qualitatively. |
