课程简介

课程名称：色彩与外观基础 课程概述： 《色彩与外观基础》是一个互动在线课程，旨在为您提供坚实的色彩与外观科学基础。您将学习到从色彩的物理学到照明、分光光度仪以及色彩数据如何测量、查看和传达色彩。 本课程特别设计适合各个行业的人士，包括质量控制和保证专业人员、实验室技术员、零部件供应商、制造规范人员、设计师以及任何评估或批准色彩的人士。 课程大纲： 1. 课程介绍： 本课程基于X-Rite的现场研讨会系列，旨在为您提供色彩与外观的基础知识和理解。 2. 色彩沟通： 在沟通色彩时，我们的脑海中会形成对所描述颜色的心理图像，但这可能导致主观性、误解和返工。在这一部分，您将学习无效色彩沟通的影响及个体在色彩感知上的差异。 3. 视觉色彩： 多种因素会影响我们对色彩的感知，如背景影响、色彩缺陷、照明及年龄。在此部分中，我们将探讨这些因素，并了解视觉色彩系统的历史。 4. 什么是色彩： 在前两节中，我们了解了眼睛的原理，并进行了对阿尔伯特·门赛尔工作的深入研究。我们将更科学地学习色彩的三个基本要素，无需学习数学，但需掌握准确可靠测量色彩的历史基础。 5. 测量色彩： 了解了观察色彩所需的要素后，我们将理解它们之间的联系。我们将通过一些实验来探索人眼对光的反应以及仪器是如何感知色彩的，最后将讨论如何有效沟通色彩差异及色彩容差的不同方法。 6. 仪器： 近年来在色彩测量和控制方面进行了大量研究。现代的色彩仪器比早期的仪器使用更为广泛和简便。我们将研究色彩测量仪器的工作原理，并探讨不同的仪器几何形状及其适用场合。 7. 发展良好的质量保证程序： 在开发色彩质量保证程序时还需考虑其他重要因素。良好的色彩是供应商和客户间商业关系的关键。我们将见识到需要追踪和控制的一系列变量。根据所需的复杂程度和具体工作流程，您可以基于视觉分析或色彩测量仪器和软件开发色彩控制程序。无论选择哪种方法，您都必须定义色彩测量成功的标准和规则。

课程大纲

Name:Course Introduction

Description:Welcome to the Fundamentals of Color and Appearance! Created directly from X-Rite's in-person seminar series, this course will provide you with a solid foundation and understanding of color and appearance.

Name:Color Communication

Description:When we describe color to another person, our mind creates a mental picture of the color we are trying to communicate. That person will formulate their own mental picture of that same color, which can lead to subjectivity, misunderstandings, and rework. In this first section, you will learn more about the impact of ineffective color communication and how individuals differ in their perceptions of color.

Name:Visual Color

Description:There are a number of other factors than can affect how we perceive color, such as background effects, color deficiencies, lighting, and even age. We will explore these in this next section, as well as learn about the history of visual color systems.

Name:What is Color?

Description:In the first two sections of this course we learned a lot about our eyes and tied everything together with a close look at the work done by Albert Munsell. We now know, beyond all doubt, that color is three-dimensional. In this next section, we will start to get a bit more scientific and learn about the three elements of color. Don’t worry, you will not need to learn the math; however, it is necessary that you understand the history that makes it possible to accurately and reliably measure color.

Name:Measured Color

Description:Now that we know the elements needed to see color, it’s time to understand how everything connects together. We will begin this section by exploring some experiments that characterize how the human eye responds to light and how this translates to the way instruments see color. Finally, we’ll look at how to effectively communicate color differences, including different methods of color tolerancing.

Name:Instrumentation

Description:There has been tremendous research into the measurement of color and the ability to control color. Today’s color instruments are more widely and easily used than early color instrumentation. In this section, we will examine how color measurement instruments work. We’ll also take a look at the different instrument geometries and when it is appropriate to use them.

Name:Developing a Good Quality Assurance Program

Description:There are other important factors to consider when developing a color quality assurance program. Good color is a commercial endeavor critical to both suppliers and customers. As we have seen, there is a large set of variables to track and control. Depending on the level of sophistication required and your specific workflow, you may develop a color control program based on visual analysis or one which employs color measuring instrumentation and software. Despite which approach you take, you must define standards and rules for color measurement success.
