Historic Look on Color Theory
The science of color is called chromatics, colorimetry, or color science. This field of science includes the perception of color by the human eye, origin of colors, art theory, therapy, the psychics of electromagnetic radiation, and effects on the brain (Azeemi). Experts throughout time have desired to decipher the composition of color to explain how and why humans are able to see colors in order to use them in numerous disciplines; from scientific to artistic. While color has been studied since ancient times, the technical workings and the modern understandings of color theory are difficult to comprehend, and one wishes to make the science more palatable. These studies have been a global pursuit. However, many important discoveries and scholars were lost over time, or inaccurately credited. The following paper takes on the historic look on color science to examine how the understanding of color has evolved over time from ancient studies until the early 19th century while unearthing uncredited experts that are not immediately recognized in modern discussion on the subject. Some experts, like Ibn al-Haytham, have been forgotten throughout time while others have been overly credited (O鈥機onnor). At first color is defined and how colors interact with each other is explained. Secondary research and criticism of color science history is used to compare, and dispute generally accepted, ideas of color theory that were discovered until the 19th century (Popova). The purpose is to give the reader a comprehensive understanding of color science, the historical evolution of the field and expose forgotten contributors
Campa帽a gr谩fica sobre nutrici贸n y percepci贸n visual en estudiantes de 8 a 10 a帽os en una I.E. Comas, Lima, 2021
La investigaci贸n tiene como objeto principal la correlaci贸n entre las variables
Campa帽a gr谩fica sobre nutrici贸n y la percepci贸n visual en los ni帽os de 8 a 10 a帽os
del colegio Juan Velazco Alvarado Lima鈥揅omas, 2021. La muestra fue de 116
alumnos para llevar a cabo su an谩lisis estad铆stico, con una poblaci贸n de 200
estudiantes. Se aplic贸 como t茅cnica la encuesta con escala de Likert conformado
por 13 preguntas y el instrumento de recolecci贸n de datos fue el cuestionario. Los
datos obtenidos fueron procesados en el programa IBM STATISTICS 25, donde el
alfa de Cronbach arroj贸 un resultado muy confiable de ,951. De la misma forma se
hizo el procedimiento para los resultados e hip贸tesis donde dio un valor de
significancia menor al 0,05 acertando la hip贸tesis de investigaci贸n y desestimando
la hip贸tesis nula. Se concluy贸 que la campa帽a gr谩fica acerca de la nutrici贸n tiene
correlaci贸n con la variable percepci贸n visual en los ni帽os, debido a que las piezas
gr谩ficas tuvieron mayor impacto
